--- Comment #1 from Ondřej Kuzník ondra@mistotebe.net --- The problem with adding has_* is that outside code still using get_* or doing what autogroup does will still do the wrong thing.
We have changed the control surface already in 2.7 (slap_add_ctrls has a different signature) and people using controls on the sending side are the ones most likely to be dealing with controls on the receiving side. Maybe we just need to put this in the upgrade docs.
