You make it sound like yarn was some sort of community a fork to plug some gaps.

Why should yarn bow out? Correct me if I'm wrong, but the yarn project didn't do the following: - put a pre-release build under a tag that looks like a normal build without a pre suffix - had documentation that expressed sudo as an acceptable way to do things to end users - then had a bug which torched machines if they ran any npm command under sudo. (which you shouldn't do anyway, but see point 2) - when pushing the fix, put hashtags in the announcements with a distinct tone of blame towards the end users.
