True (I did that but could have done it earlier.)

Yeah, that’s right.  I’m not saying it would have been easy to avoid the
delay; it’s obviously very tricky to get right, and gets more difficult
as the package collection grows.  Clearly you and Marius did a great job
at fixing bugs and making sure we’d make progress!

My thought was that fixing specific dates might help get everyone
psychologically prepared and ready to focus on stabilizing the branch
when the time comes.
