Quicktime 7, Carbon, Ink, Apple's hardware RAID support predicted to be gone in macOS 10.1...
QuickTime7, Carbon, Ink, and Apple's own hardware RAID support look to be on the chopping block for macOS 10.15, along with the removal of support for 32-bit apps.

It is anticipated Apple will be revealing the various changes it will be making in macOS 10.15 at WWDC 2019 on June 3, and in the run up to the event, leaks and rumors are surfacing with claims of what Apple will be introducing or removing in the update. While many of the reports have centered around user-oriented elements, there are some that developers may also want to be aware could occur.
According to developer Steve Troughton-Smith, macOS 10.15 will lose support for Carbon and Ink, the former being a C-based API, the latter being Apple's handwriting recognition technology introduced in Mac OS X 10.2 "Jaguar." QuickTime 7 and QuickTime plugins are also reportedly disappearing, which could affect some applications that take advantage of the technology for media output.
The tweet advises PPTP will be removed, though Apple formally stopped support for the VPN client in macOS Sierra 10.12. It is still currently possible to use PPTP, though through third-party VPN clients.
Apple hardware RAID support extinction comes as no surprise, as the hardware needed for it hasn't been produced in many years, under the names the Mac Pro RAID Card and Xserve RAID Card. External RAID hardware and software RAID arrays generated in Disk Utility do not appear to be affected at all.
The latest list of changes is only some of the items that are expected to change in macOS 10.15, with the main confirmed item being the discontinuation of support for 32-bit applications. Apple has warned of the change since High Sierra, with macOS Mojave the last to support 32-bit apps.
Other speculated changes include the introduction of Siri Shortcuts and Screen Time, an update to allow the Apple Watch to perform more authentication-based tasks, and standalone apps for Music, Podcasts and TV.

Dashboard isn't the only thing gone in 10.15 -- so is 32-bit app & plugin support, Carbon, Ink, QuickTime 7 & QuickTime plugins, PPTP, and hardware RAID. You will get Python 3.7 and Ruby 2.6, at least

I love the eco-system of Apple products. they need to quit killing stuff that just works.
I won't miss anything mentioned in the article except PPTP.
Tech is always going to move forward and change has to occur.
Some people will always complain about certain changes when they happen, but there is nobody forcing anybody to upgrade.
If somebody absolutely must have or relies on some old software or hardware, then the solution is simple, just don't upgrade. Keep using what they have. I still have machines running OS 9, and I recently installed SSD boot drives into them, mostly for fun, as opposed to necessity or need.
I'm always up to date with the latest Mac OS version on my newest machine.
I was going to say something similar. Apple’s RAID solutions have sucked big time for a long time, and are a clear and present danger to your data.
My take is that Apple should just get the hell out of the RAID business because there are plenty of third party solutions that do it very well.
I remember buying my first iMac in '99, and the iMac just said screw the floppy drive, I don't need one.
It was the first legacy-free PC, according to wiki. It was also the first computer in the world to have something completely new at the time, USB exclusively, with no legacy connections.
I'm not one of those customers who wants the opposite. I want Apple to move forward. If I want nostalgia and old hardware and outdated software and connections, I'll just fire up one of my old Macs.
you need to pull up out of the weeds and take a bigger picture view than “Apple dropped support in Mojave and only gave 3 months notice”.
Whilst that’s true, they announced deprecation of PPTP 2 years prior with Sierra.
its irretrievably broken as a VPN protocol, and there are complete, prebuilt tool chains that can crack PPTP traffic.
The theoretical problems were identified nearly 20 years ago, and by 2013ish, people had built simple to use tools to bust it wide open.
These are fundamental flaws in PPTP, not simply implementation bugs.
Using it in 2019, is not defensible from a security perspective, as it’s been broken for so long, and known to be broken at a theoretical level for even longer. Using today is arguably worse than doing nothing, as you a pretending something is secure for theatric purposes knowing it just isn’t any use at all.
Positioning it as “Apple did not give organizations enough time to migrate” when they have a 2 year lead time before dropping it, the thing they need to migrate off is a dumpster fire that is well known to be deeply flawed & vulnerable to widely available attacker tools for the better part of a decade is not a reasonable criticism of Apple, but actually a very deep criticism of that uni’s IT team.
