When Windows boots from UEFI it can load just its system-disk driver via
the firmware and the rest of the OS using its own driver; that ought to
make Windows boot times much faster.  I'm told that an EFI framebuffer
could make PV graphics easier too, but I don't know anything about
Windows graphics drivers.

Also, eventually some server SKUs may go EFI-only, or we may need EFI
for system logo tests, but that seems unlikely to happen soon.
