That sounds like a good idea for PyTypeFromSpec. I don't think we're planning to support vectorcall in PyTypeFromSpec for now. That's maybe for 3.9 when vectorcall is no longer provisional.

For static types I either wouldn't bother at all, or only check in debug builds and fail with PyFatalError. So basically an assert(...)?

Yes. That's the usual way to let C extension authors know they did something wrong.
