More interesting is the port seems to be screwed in, suggesting it is replaceable. The ports will get more of a beating with USB-C vs the cable with Lightning. 

Ok, there is high wattage phones for charging. What is the battery life going to be? Ok so I can see some reasons to use it, airports and commuter stations. Most of the time you don’t need it. You end up with a laptop charger so you can charge your phone in less than ten minutes. Then that extra wattage is not being used. The phone cpu and gpu is going to use that much wattage even during high usage. We finally found a phone chip that beats Apple, though we recommend heat resistant gloves. I’m still using my 5W charger at night. That same 5W charger still fully charged my phone, even when I’m playing Minecraft. I’m not changing my phone to have such high charging power.

You are not going to be able to pump a full 100W in to a phone, even with a full capable cable and charger.

The impedance of the load (in this case the charging phone) determines the power draw. The source (charger) doesn’t pump more current/power into it (even if it has the capability) than the load’s impedance dictates at a given voltage level.

There are already and will be phones that will draw 200 and even 300 W.

As for this MFI USBC rumor, I was expecting it. It's just going to be a "superset" of the USBC standard, which is already hyper convoluted with its support of a gazillion different protocols. It will be Apple's way of guaranteeing a cable will work with iPhones. There will be USBC cables out there that won't be compatible. If the Pro models support Thunderbolt, which I'm expecting, that definitely means there will be USBC cables that won't support TB or other power profiles.

Oh really? What phones can handle 200W or 300W? Name one please. What connections are they drawing power from? How are they dealing with all that heat?

Absolutely, however you will have people who will complain that they can't get the 100W from the charger and cable in to the phone. They will blame Apple for that.

It is extremely unlikely that apple will require certified cables, as I think that would break the standard. I think they might warn of non-certified cables and they might have a high security mode that will allow you to restrict cables used to secure or certified cables. We have seen several stories, where security researchers have made cables that look normal, however have circuity that allows traffic to be snooped and sent back out wifi or bluetooth. To make it the default for all phones will simply get Apple in trouble. 

You will not have full capabilities of USB-C/Thunderbolt on any phone, Apple or otherwise. You are not going to be able to pump a full 100W in to a phone, even with a full capable cable and charger. the phone cannot handle the heat and the battery will not last long. Similarly, you are not going to get full USB-4 or Thunderbolt speeds out or in to the phone. You need the right chips, and the chips must have the bandwidth.
