Well, it looks like a coup.
The poll was closed by its supporters a few days ago, having run for barely a week. Fairly outrageous, considering most things are allowed to run for a few weeks minimum, but I assumed it had been closed because with less that 65% support there was an evident lack of consensus.
However, some dev felt differently, judged there to be a consensus, and we now have rollback enabled - without any waring whatsoever.
Admins can switch it off or on, but there's absolutely no agreed policy for when, how, and how disputes are resolved. The inevitable bureaucracy will follow.
This to me is the definition of disruption and the antithesis of consensus.
