Yes, you are right and part of the confusion comes from the comment next to the release call saying that set_alt or a future bind will set "claimed" again since that's not going to happen. My latest message clears that up and proposed various options to handle this for me. I've also sent an RFC patch adding a hook that I've tested with simple configs and works. I'll do more testing tomorrow with more complex setups.
