Anything that can help guide people to being more pleasant has to be a good thing. It doesn't matter what kind of help or hint or rephrasing feature is added, there will always be ways to circumvent the ideology of the feature, but to that I would say do you really want people in your community that will make such an attempt when they know that it's there for a reason? I like this feature and I hope community members everywhere will appreciate the thought that stands behind the idea. Of course it, like any other kind of censorship, has to be measured and it will be up to each community administrator to make that determination; the key word there is 'measured' otherwise it could be seen as kind of totalitarian, which is not what it's meant to be. Good call, good feature, far more intuitive than just word censorship 🙂
