Comment (by tscrim):
Something I've come across is that I have wanted to check category
containment of objects (along with axioms), but with not necessarily
knowing what the object's base ring is (or if it even has one), I couldn't
get this to work easily. In particular, the category containment checking
had trouble differentiating between when something was in
`Algebras(Rings())` and Algebras(ZZ)` IIRC. So I'm +1 for moving
completely to singleton categories.
