It's not about any "despite these early problems".

It's about "clearly we're not doing things at all like Windows, and
it's just broken".

The thing is, we will never be able to match Windows exactly. It may
well have random hardcoded quirks we simply don't know about.

I'm perfectly happy with you aiming to use _CRS. I am _not_ happy with
you then using that as an excuse to then do things that don't work.

We will NOT start doing random BIOS-specific quirks just because
top-down allocations hit other bugs than bottom-up ones do. Just no.
We'll continue doing that we have tried to do, which is to perhaps
have quirks that are specific to *hardware* (like the ones in
drivers/pci/quirks.c) and just filling in stuff that some BIOSes are
known to get wrong.

That's a maintainable approach. But it's maintainable ONLY if we then
don't do other random changes that invalidates all the years of
testing we've had.
