Thank you, I like it better than `__getattribute__` solution.

I looked at all of them, and I don't think we need to leave out more than you
already did. However, I found a source of null cursors, and left a comment
there.

No, mapping of null cursors to `None` is an invariant for the whole `Cursor`
class, so your new decorator should be put on almost anything. Maybe worth
leaving comments on methods which are not decorated, to make it clear that it
is a very intentional omission.
