Yes.  But in brief, we also don't go fully down the ACPI path for x86.
But we can do "something".

I assume you mean EDK II when you say UEFI is open source, and yes
that's true.  But I've said in other places (and other contexts) choices
make all projects stronger.

I think that takes too narrow of a view.  If silicon is sold, someone
will put it somewhere.  And if there's firmware that works, and the
buyer can modify to suit their design, they'll use it.
