I really like your idea but I assume it's quite rare to implement the "stop/del/leave/disconnect" callbacks and at the same time forget to implement the "start/add/join/connect". You will probably find out pretty quickly if the "start" functions are missing, while it might take some time debugging why you lack the "stop" functions (reinitialization issues/ resource leaks for example). With that said, don't take my word for it, I was only following the existing pattern and I assume someone else had a good reason in the first place.
