I firmly believe the author's stance should be the default policy of just about every open source project. I don't even write my own code anymore, I sure as hell don't want to deal with your code.
Give me ideas. Report bugs. Request features. I never wanted your code in the first place.
You believe. So it applies to projects you maintain. It doesn't mean it applies to project I maintain, or anybody else maintains. So this shouldn't be any more default than any other mode. And probably less default, since people generally developed other conceptions about "defaults" of etiquette in open source projects over the last 15 years.
