What about all the macs that can’t run 10.3.2? Did a security update fix those systems?

Those Macs that can't run 10.13.2 most likely are no longer by Apple.  

Using the 'dosdude1' patches, many older machines like the MacBook5,1 from 2008 can run 10.13.2 just fine.

Because of the way photos/videos are taken in IOS 11 in a more svelte manner with the new codec, it
may be useful for Mac owners who archive photos there to upgrade to MacOS High Sierra first.

That way, HEIF photos and HEVC video can be transferred in their new format without being converted to
to JPG first.   So what?  Because many of us periodically transfer photos then immediately delete them from the
camera, unless one upgrades the Mac first to 10.13, they would be relatively bloated in the JPG/H.264-based
Sierra 10.12 iPhoto/Photos libraries, albeit compatible.

However, there is a setting "Keep Originals" in iOS 11 which can aid with the transition.

What's the equation to get that 5 minute buffer for a 20Mbps content with a 12Mbps bandwidth? 

The waiting time for starting a progressive download is governed by the formula

      BufferTime = ((FileDataRate / ConnectionSpeed) - 1) x Duration

taken from Ben Waggoner's discussion at:

http://books.google.com/books?id=lDzDRieofpAC&pg=PA158&lpg=PA158&dq=buffertime+formula+progressivedownload&source=web&ots=7A5iLUpoju&sig=YowK15KR4xIHIgUH9D3HB8kc7x0

so, for your example, waiting 300 seconds = ((20Mbps / 12Mbps) -1) x Duration
you could only play a 7 1/2 minute video clip before rebuffering.

I wonder if older Macs where Sierra runs through a patch will support APFS. Here, one machine in question is a 2009 MBP. 

I have some concerns about this. I wouldn't expect it.

In a different thread it would appear that it works just fine: https://forums.appleinsider.com/discussion/200435/high-sierra-runs-on-all-sierra-capable-hardware-starts-process-to-kill-32-bit-apps/p2

post by MacPro. 

Which makes me wonder: how can I link to a specific post in a different thread?

The posts by MacPro in the other appleinsider thread refer to 2010 machines which are already on the official Sierra-supported list.
For older machines like 2008/(early- and mid-) 2009 MBPs there are still issues with High Sierra.   For example, folks report that the High Sierra
install first updates the EFI firmware to support APFS upon boot.  So this may require EFI firmware hacking at a minimum, as Apple
is not likely to release firmware updates for unsupported gear.  Details unfolding at:  https://forums.macrumors.com/threads/macos-10-12-sierra-unsupported-macs-thread.1977128/ ;

NHTSA also went further to report that accidents (at least those enough to trigger an airbag) are reduced by nearly 40% for
Teslas equipped with autopilot, from 1.3 crashes per million to 0.8 per million.   Not "left turn across path" stuff quite yet,
but injury-level accidents.  This will only get better over time as new subsystems (better interpreted radar, sonar, and vision etc.) kick in.
