Yeah, in this case, I would expect that one could gather enough info from "b.equal(order_.get(Order_.orderType)",
as this is a well-known model type – should have full info.

Hmmm, would a "noop" really work here?
As you have to choose what to use – ordinal or name, from enum,
based on what the entity model has in config for this property (which @Enumerated(value = EnumType.XXX)).
