We do have VTABLE methods like VTABLE_type that don't have any
PIR-facing interfaces. In those cases they are used internally to get
the type id numbers for use with PMCs. Now, if we want type ids to go
away completely in the future, this vtable method will be deleted and
replaced in most cases with VTABLE_get_class or something similar.

In either case, it's not unheard of to have a VTABLE method that's not
accessible through an op, and can be useful for internal purposes.
