I'm sympathetic, but the same arguments were made against the
Foldable-Traversable Proposal. See for instance


Since that wound up going in, I think this ship has sailed.  Types are
going to become increasingly polymorphic in the Prelude.  Though I wish
this weren't so I've come to accept it, and I doubt attacking it head on is
going to get anywhere.
