I don't follow -- can you please elaborate?

If you don't want to do anything with the 'types' argument, you can simply
ignore it.

The problem of identifying whether arguments have valid types or not
remains unchanged from the situation with __add__ or __array_ufunc__.
'types' just gives you another optional tool to help solve it.
