I've seen several people jump from "I'm getting pushback on foo" to "nothing at all can be done" recently. It's bogus reasoning. My view is that the project is no longer in its infancy, where quick and sometimes arbitrary changes could be made. That may have scaled early on -- but now we have hundreds of developers, thousands of contributors, and bazillions of users. Now we need consensus and buy-in and roadmaps. Next, rather than compare who has done how much hard work and when (and you both have), Attilio has been doing a lot of work on locking over the past few years. If he (and possibly the people who have been looking over his shoulder) have a view on how we should move forward, I think they have earned the right to state it. Finally, IMHO, hyperbole can turn off developers too. mcl
