Github user knusbaum commented on the issue: https://github.com/apache/storm/pull/1468 -1 I am generally opposed to this. Most PRs only have a small number of commits and aren't a problem. For PRs with a large number of commits, it's simple enough to ask the contributor to squash their own commits. I'm not sure I see the benefit in adding another script, which we will have to maintain, in order to do something we should rarely be doing. Also, I worry that having this script will lead to a sharp rise in totally-squashed PR merges, even when there's not really any benefit (and in fact, loss of authorship info) since some people are likely just going to use the script whenever they're doing a merge.
