This is wrong at so many levels. Of course we don't care about "progress" or "woops I fucked up" commits, but people also do commits for things like coding style, and these commits should be keep separated from the others, and DO NOT warrant a separate PR. If it is about changing all tabs to space in a file, for instance, different PRs will be hard to work with, because of conflicts. Also, people who write WIP commits should learn how to squash them themselves, and give them a meaningful commit message.
