So here is what i think the criteria should be:

If Avahi is popular and widely deployed (I dont use it anywhere), it
makes no sense to revert. 
A middle ground is: instead of rejecting the nonsense passed, maybe a
sane thing to do is a kernel warning for a period of time (sort of like
feature removal warnings).

The only way to keep the patch IMO (if avahi is widely deployed) is if
common distro policy is such that they will immediately fix and
distribute a new avahi even when this breakage is with a kernel that
distro wont support for  a year.

hope i am making sense.

cheers,
jamal
