After Jimbo's intervention, it looked like we were going to get flagged revisions on all BLPs. That seemed like a great step forward - although not nearly enough. (Flagged was never going to be a panacea, since less credible untruths (which is the really damaging stuff - as opposed to obvious vandalism and simple abuse) would end up getting reviewed sloppily and not picked up.)
However, today sees a pile on for a really really watered-down version even of this. (See here.)
This new idea will allow any autoconfirmed user to mark versions as OK. The net result will be (perhaps) to reduce obvious IP vandalism, but it does nothing to protect BLP subjects against determined detractors.
Indeed, it seems the aim is that this will simply be used on articles currently semi-protected (and NOT all BLPs). So it offers nothing at all to the BLP subject. Before, if semi-protected, the new user of IP could not edit, now IP or new user can edit in a limited way. Meanwhile, if this passes it will give the sense that the community has "done something" and set back the cause of doing anything that actually helps.
A sad day.
This new proposal is an effective spoiler.
