Firstly, there is the backwards-compatibility issue to deal with after
removing <+>. The same applies for composeAll.

Also, I find the <+> operator to be slightly more convenient to write
than `mappend`.

Only the first point is an issue that could be addressed by a textual
substitution-based config updater (or better-yet, one using the AST
parsed from haskell-src-exts), but that has not been done yet.
