Although initialization cost of each one type is small, time for _Py_Ready() is not negligible. And ABC.register() too. Import time for _collections_abc is not negligible too.
I agree that cost of adding three builtin types and register them to ABC will be negligible or small enough.
But I think it's good to know before merge.
