I did this to a) make it backwards compatible with what was there before and
b) because I was reluctant to start creating a big type hierarchy. This way
I can
have it take PetscFE or PetscFV and maybe something else. Then I figure out
where a type hierarchy makes sense, or a single type, or this just does not
at all.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
