So your answer can be summed up as: 'we wont do what makes sense technically
because others suck even more' ?

And it's not just the kernel<->user interface (which btw., for the case of X
is far narrower than what KVM currently has to Qemu).

The issue is a basic question of software design: does kvm-qemu really make as
much sense without the kernel component as with it? The answer is: it will
borderline-work with CPU emulation (and i'm sure there are people making use
of it that way), but 90%+ of the userbase uses it with KVM and vice versa. It
is really a single logical component as far as maintenance goes, and
tools/kvm/ would make quite a bit of sense.

But i digress.
