I agree, I think it's really unfortunate the way this has played out. If it weren't a feature which I think some folks are actually using, I'd be tempted to say lets revert the whole thing, given the nature of the long-standing issues, and that it's, umm, not exactly been actively maintained by the original author.. :( > What do folks think about adding a config option for this feature (or even > separate ones for abandon & adopt?) and disabling it by default? Obviously the risk here is that the disabled bugginess then persists forever, so if we go down this route, I'd like to get some assurances from those involved with or interested in this feature that the problems will get worked out during Kilo, with a view to re-enabling in future. Also, this is a terrible experience for users from an API versionining perspective - we probably need to move towards an discoverable optional extension model, or micro-versioning, so folks have some chance of figuring out what functionality exists in a given heat endpoint. Until recently I was of the opinion that incrementally adding things to the API was OK, but this is a prime example of why it's actually not IMO.
