You are probably confusing derive with uniplate, which is a library
for generic traversals. The derive package is about automatic instance
derivation. But you're right that we'd have to choose a traversal
library, out of several available ones. I thought Data.Traversable
would be a good choice since it's already in the boot libraries.

Yes, although putting the doc info in the .haddock file would also work.
