A related point that occurred to me about the convenant which Torvalds has included is the "Scope" section. It looks like it leaves most of the details to the project maintainer which I suppose is a good thing. However, an explicit statement about where the whole thing doesn't apply would be useful.

If a person has a political or other opinion and is very strident about it in every sphere (twitter, personal blog, facebook etc.) outside of the project, the convenant should explicitly allow this. That way, it sounds more like a "this is our house and these are the rules you should follow if you want to enter" vs. "you should be a certain kind of person in all aspects of your life to be allowed in here". The latter has too much overreach IMHO.
