While I agree in general, one comment.

We haven't decided about the patch yet.  We may decide to bump up the _REV
to 6 when ACPI 6 is out instead.
I'd be happy with this too.
That said the whole using of _REV to special case Linux is broken by design
and should be stopped immediately.  Especially when it is done by comparing
the return value of _REV to a specific number (like 5 or 3).

Yes, it's been made clear to me that this shouldn't be used in the future.  I've shared that feedback to my BIOS architecture team.
