Thank you for the feedback. I was trying to state the facts, but I
understand how this could be read as a criticism.
As you say, mistakes happen -- and when they happen on the stable
branches, there is very little to protect the end users. Could we
enhance automation to prevent this situation? For example:
- bin/.cherry-blacklist lists commits that should never be shipped on
stable.
- bisected bugs -> update the blacklist
I can't think of a way to automate that, but it would have highlighted
one of the instance where we shipped a regression in a 17.3 point
release.
