Once something is deprecated, it remains in QEMU for a minimum of two
release cycles, before being deleted. At any time in that deprecation
period it can be returned to supported status, if someone provides a
good enough justification to keep it.
IOW, we can deprecate this now, and you still have plenty of time to
investigate more.
