I'd imagine 'breaking the build' is, for almost everyone nowadays (and in most situations), a very minor issue. But it's still, all else equal, a net negative, however small.
Breaking a build once, for whatever reason, probably isn't a big deal. But breaking a build frequently certainly could be.
If you break our build, your pipeline fails and your code is not merged. Simple as that. The master branch doesn't break, because we don't merge broken code into it.
