Hi Jonas,

Maybe #16507 would make this work too if the CuspForms construction were
implemented as a composition: ModularForms followed by CuspidalSubspace,
where CuspidalSubspace would be a special case of SubspaceFunctor (i.e.
with coercion_reversed=True in the terminology of #16507)?  Then
pushout() would remove the application of CuspidalSubspace when merging
the two constructions.
