Difficult to do a one-size-fits-all process. Am certain that Microsoft is finding cases where they my need to revise some of the lists and requirements.
The marketplace also can have an impact here. Am noticing that some outlets like NewEgg are out of certain TPM modules. Am thinking that some have been out of production and will be hard to get until 'someone' starts to build them again.
Wonder if some devices are failing due to lack of current Bios update as well.
Won't be an overnight process to address all the issues but some general guidelines will likely emerge as this gets prepared for Insiders. They did say many of the Win 11 components ? features ? were tested with Win 10 already so there will be 'some' compatibilities.
Some great questions posed in Community and lots of great ideas and references. Users can also report suggestions or problems to Feedback Hub and report on success or failure with PC Health Check.
