Ideally, after branching we will check buildbots are happy to compile the branch. In the past it was some obscure issue with build system which was only visible in a fresh build. The build takes a long time (slow compiler, builder VMs not being super fast), and coudl easily take 50min or even more than an hour.
The 2.92 is the second release when at the end of the day the branch was not done yet, forcing either baby-sitting builds past a day full of weird and wonderful adventures or forcing to postpone branching/announcement for the next day.
Seems that a lot of time was waiting on some tweaks in the interface to happen prior to branching. Why is it so? How can such tweaks be avoided at the branching and happen sooner? Or, maybe, we should allow such changes after the branch? Can they be considered fixes?
Or just relax expectations on builds ready immediately.
