First of all, we longer care about ABI compatibility of PyTypeObject.

Second, it is extremely unlikely that the class will use vectorcall: the only way would be to inherit from a base class that uses vectorcall, but there aren't any subclassable classes using vectorcall in CPython. If the class doesn't use vectorcall, then it really doesn't matter: tp_vectorcall_offset is unused in that case, just like tp_print.
