Not surprising at all, with these kind of local changes guesswork submissions.

Why, what is the reasoning and rationale for this prosposal? How does it meet
the criteria for all systems changed on your use case, what are the results..?

No, there is no proof this is needed. It's not justified, and not reasonable.

Hello Hagen,
This looks like a local testing, proof-reading session instead of development.
Start by enumerating all variants of boot, including network and diskless, and
don't forget other platform hibernation support, not just your own one laptop.
Test and make valid reasoning what will happen with the boot process to cope..
