Ok. That explains its history, but it also clarifies that changing the
u# implementation has *no* effect whatsoever proper operation of s#.

Therefore, I still think that u# should reject string objects, instead
of silently doing the wrong thing.

Yes, that would be nice. The only use of u# I can see is that it gives
you the number of Py_UNICODE characters, so that the caller doesn't
have to look for the terminating NUL.
