It's up to you really. If you won't have a version of qemu that can do this
by itself, it may make sense to keep it around for a while. You might
want to include the version of your current qemu port is based on
qemu-2.x but not upstream, you could include a qemu-2.x.dts file
here, and have the future 3.x port provide its own.
