I would rather move toward headers including only *types.h from their
dependencies.  Reducing such dependencies is a breaking change so we
need to be judicious and document it, but adding dependencies
gratuitously is the wrong direction, IMO.  (It slows down incremental
rebuilds of PETSc and user code.)
