Yep, sounds good (with "no-op" in this case meaning "just return self").

It just occurred to me that it could be interpreted as a breach of the moratorium. On the other hand, according to PEP 3003:

“The case for adding a method to a built-in object can be made.”

This case seems even lighter than adding a new method.
