would rather seem to indicate that the bug is in python-fill-paragraph
(maybe the bug is that python-fill-paragraph should never be called
directly as a command, for example).

No, the current definition is on purpose.  As the docstring of
fill-paragraph-function indicates:

   ...
   If the function returns nil, then `fill-paragraph' does its normal work.
