I think that argument clinic knows if the built-in function is
supposed to be a method or a function.  It doesn't look too hard to
add a new flag METH_IS_METHOD or something, which would be taken in
consideration in the common cases, and which can be added manually OR
used automatically by argument clinic.  This would not be a 100%
solution out of the box, but if the new wording is right, it shouldn't
be a problem.
