Hi.  I work on the OVMF project which Stefan mentioned.  I definitely
can't speak for the qemu/kvm project, but I'll give my impressions
from my OVMF perspective.

I think qemu/kvm has some interest in supporting UEFI, but they are
(understandably) concerned about losing legacy bios compatibility.
Additionally, they do not want the user to have to choose between a
legacy boot rom and a UEFI boot rom before starting the VM.

We would also like to support Xen in our OVMF project. (EFI in HVM
guests)  So, if this project is interested in leveraging our OVMF
project, then we could try to help support this task.
