I vote:

S > A > F

Rationale:

To me, S is the least bad option. It's self-contained and follows the
precedent set in other distros. It obviously needs to be time-limited as
we expect systemd-resolved to continue to develop and at some point
become a reasonable replacement for avahi-daemon.

I do not find option A as objectionable as some others do. I think it's
OK for packages to adjust the behaviour of each other, when coordinated.
This isn't a situation where both sides think that this is the right
approach, so I can understand others voting it below F.
