I think this is unnecessarily restrictive. It's unnecessary because a
verifier that wants to handle multiple versions can always incorporate
a routine per version. It's restrictive because a later version might
want to disavow an earlier version.
If you want to change the semantics that much, like I said, give it a
different name.
