Probably not!

So, do you mean that let kernel provide a per-VMA allow/disallow
mechanism, and
it's up to the user space to choose between per-VMA and complex way or
global and simpler way?
QEMU could do either way. The question would be if a per-vma settings
makes sense for NUMA hinting.
From our experience with compute on GPUs, a per-mm setting would suffice.
No need to go all the way to VMA granularity.
