Ticket #16507 should solve this (at least to some extent) in situations
where there is a coercion B -> A instead of A -> B.  (Here B is the
object resulting from a functorial construction applied to A; this can
be used if B is a submodule of A, for example.)  This won't address
things like (base ring, cusp forms) -> (modular forms), though.
