Sorry it took me so long to reply.

You might be right, but I'd much rather not have to check it really does
before relaxing the dependency (which would also mean it couldn't be
automatically generated).

I don't necessarily want /you/ to, I just want to be able to myself
without anything breaking. In fact, having thought about this a bit more
I think this already is the case, as nowadays a cabal package using the
readline package will have to specify it explicitly rather than GHC
noticing it uses an appropriate module and pulling it in automatically.
Thus an automated tool would generate a dependency on a suitably named
package and it would all work fine. Well, that was easy  :-)
