Reduction to absurdity: if (almost) everybody got to add something, you would have an undifferentiated mass of scar tissue. There needs to be some discrimination of what changes "fit" the language.
Of course, "fit" and beauty are in the eye of the beholder :-(
It doesn't quite work, because Steve says "you need to be more open to fixing annoyances" and Rich responds "Look what a mess would it be if we fixed everyone's annoyance!". There is a big continuum between the place Clojure is now and the hypothetical absurd described by Rich.
Would someone care to explain?
