I don't agree that not-OSI means proprietary.

I agree that the FAT driver is not 'free software' and I agree that is
a problem for usage with free software projects, such as QEMU. This is
a big deal, but unfortunately, as an Intel employee, I think I've done
as much as I can to address this.

It couldn't hurt if more people that actually care about this spoke up
on edk2-devel about the issue, or perhaps within a UEFI working group.
Because, I know that they've stopped listening to me about it.

No, but I've always thought that QEMU was happy to have alternative
firmware projects.

Where has 'linked' in terms of the GPL ever been anything other than
actual executable linking?

Is this a licensing issue? I thought this was a "let's save time by
doing it in one place" thing. I'm pretty ambivalent about this
feature, really. I don't think it is even worth all this bickering.

I'm certain OVMF has ACPI issues on QEMU, but I don't think it is a
huge deal to resolve them independently of this feature.

I was not a huge fan of supporting this type of thing for Xen in OVMF,
but it does seem to work fine.
