At the 20k level, I pretty much agree with everything John has said. This smells to me mostly of a way for the IESG to have an friendlier way of shutting down a WG without huring people's feelings. Sorry, but I think this missed the point. (I would be fine with individual cases being closed due to OBE, but even then the reasons will be nuanced and not covered by a broad statement.) OBE is not well defined, and folk will just start arguing about whether something really is OBE or not. I.e, we're just moving the problem elsewhere. In some cases, the problem may be easier to solve this way, but in others I doubt it.

I think this is right. And the question isn't whether an effort is OBE, but rather: is the effort a still a good use of IETF cycles. That can be measured in many ways, including: - is there (still) a real customer for this work at the end of the day? - is the effort making decent progress without excessive intervention/help from the ADs and other non-WG parties? - will the effort require serious cycles from the IESG (and others) when the WG declares it's finished and it goes to IETF LC? (And will that effort be worth the benefit?) - is the effort sending misleading (or incorrect) signals to the broader community about whether the IETF really is developing a useful solution in a particular area? That is, all-in-all, does it make sense to continue the WG, or should the IETF cut its losses and move on? A good number of the above questions have little to do with whether something is overcome by events.
