I would think that AnyEvent::DNS already supports caa records, it just
doesn't use the caa name but gives you the numeric code, wouldn't that
have worked for you?

I'm a bit split - on the one hand, the patch is simple (and I have applied
it, so it will be in the next release), on the other hand, this will
likely break all existing users of caa records with AnyEvent::DNS (which
hopefully don't exist).

So at the moment, I am inclined to officially not accept further such
patches on the ground of backwards compatibility, at leats in less obsucre
cases.
