Apparently this isn't possible with ansible at the moment. I had a conversation with mdehaan on IRC and it boils down to ansible not having a directed acyclic graph for resources, making things like this very hard.

Asking mdehaan for an example e.g. authoritatively managing a sudoers.d directory he came up with these things:

14:19 < Robe> mdehaan: HM
14:19 < Robe> mdehaan: that actually looks relatively sane
14:19 < mdehaan> thanks :)
14:19 < Robe> the problem I'm seeing is that I'd have to gather the managed files myself
14:19 < mdehaan> you would yes
14:19 < mdehaan> ALMOST
14:20 < mdehaan> you could do a fileglob and ... well, it would be a little gross

14:32 < mdehaan> eh, theoretical syntax, nm
14:33 < mdehaan> I could do it by writing a lookup plugin that filtered a list

14:34 < mdehaan> if that plugin existed, for instance, and iterated across lists in A that were also in B
