I'm not sure I've ever been involved with a WG where you could have gotten consensus on any of the above enough to publish it. Nor can I think of many WGs that have the excess energy to do this work. Even getting consensus on a summary of where you ended up is quite tricky. Because of who I'm responding to I'm imagining getting consensus on a summary of where the RRG ended up on the discussion of well whatever it is that they were discussing regarding id/loc split and all that stuff. WGs aren't particularly easier in this regard. You could probably get consensus on which set of documents a WG published in most cases, but if you added any context, say a discussion about whether those documents are still good ideas, it becomes a lot harder. This has value. I've supported certain aspects of the ISD proposals, of some things coming out of newtrk, etc. One aspect I've always disagreed with is proposals of this type that proposed to be generally applicable across the IETF. I agree that writing down where we were, where we are, what happened in between can be valuable. However it is quite expensive, and we need to balance that.
