PS6: 
Framework is launching a Chromebook edition:
https://frame.work/ca/en/laptop-chromebook-12-gen-intel

If this chromebook is like others we've seen in-tree, I expect some code drops here that should help this project along. I also expect minimal hardware differences if any between this and the standard versions.

Also, in the description is this gem:

"Since the Framework Laptop Chromebook Edition chassis is compatible with Framework Laptop Mainboards, there is always an upgrade path available if you want to move to a different OS or processor in the future."

To me, it implies moving from ChromeOS to anything else requires mainboard replacement. Your being provided a bootguard-free unit also means a bootguard-free mainboard can be offered as a DIY option. I expect anyone choosing this option would run Linux and not care whether TPM works or not, or if Windows 11 would install. The same Framework chassis can then carry 3 types of mainboards: Standard board for Windows 11, ChromeOS board, Bootguard-free board for coreboot+whatever (presumably without vPro).

In my opinion, if this code can completely boot the hardware to Linux login prompt minus bootguard, take it. Add a disclaimer. Leave FOSS purism to libreboot. If you have a channel open with Framework, please advocate for bootguard-free mainboard option. My perfect laptop is a Framework convertible tablet that can run coreboot. I'm still waiting while hanging on to my X230 Tablet, which is a "close" second.
