If they are a general facility, they should definitely be moved;
the main repository for them should be the Emacs repository.

      Currently, some
    fancier capabilities of MH-E are only availble if the user has also
    installed a separate recent version of gnus since the Emacs version is
    too old.

If you distribute MH-E outside of Emacs, you can distribute whatever
you like with it.
