Please do file a bug about this. Python's interface to readline is
pretty old, I wouldn't be surprised if more functionality could be
added. Regarding operate-and-get-next, I searched for "gnu readline
operate-and-get-next" and found some feature requests about it for
Sage and IPython (not sure of the status there), plus an explanation
of why it's not part of GNU readline: it needs to be implemented by
the calling app because only the latter knows what constitutes a
complete statement. I think either of these would probably be a fun
project for an aspiring core developer interested in improving their C
skills.
