Upstream perhaps, but there will still be substantial use of
qemu-traditional.  XenServer for example will be maintaining both qemu's
for the forseeable future, and I expect other larger distros will.

(Also, these patches have been pending since early 4.2 without specific
concerns against them, but I clearly didn't badger enough to get them
committed)
