I disagree. Not being able to do an update for a whole three months
would block any of the features relying on kernel interfaces for the
same time (or even longer, if the kernel release schedule aligns badly
with QEMU freeze.)

Issues with things being reverted in the Linux headers have been rare
(and the ones I remember were because we did not merge from Linus
master, but from some other tree that changed before being merged). I
don't think it is worth slowing down development because of those rare
issues.
