This has nothing todo with them being in separate source repos. We could
update QEMU to new major feature releaes with the same frequency in a Fedora
release, but we delibrately choose not to rebase the QEMU userspace because 
experiance has shown the downside from new bugs / regressions outweighs the
benefit of any new features.

The QEMU updates in stable Fedora trees, now just follow the minor bugfix
release stream provided by QEMU & those arrive in Fedora with little
noticable delay.
