Instead you should have 3 packages here.

avahi that ships the non-gtk linking bits.
avahi-gtk2 that ships the gtk2 library.
avahi-gtk3 that ships the gtk3 library.

This wasn't done originally as we lacked the manpower there and hoped
that gtk2 consumers will go away soon anyway. If that isn't the case,
the work should be done long ago. I hear there have been various
dependency issues already anyways due to the splitting not having been
done.

If there are no more avahi-gtk2 consumers, you could drop the gtk2
support altogether and maybe not need the splitting.
Then the question is if you name it USE="gtk" or USE="gtk3" to build
the gtk3 component.
Either way, consumers would USE depend correctly on which they need - I
don't think it's magical, so consumers would always actually link to it
and a clear USE depend can be in place.

So in an ideal world, you wouldn't have any USE=gtk* whatsoever here
anyways.
