Great reply to this mindset. The chance that anyone who makes this claim has actually evaluated enough (or any) JS projects to see why they churn is effectively zero.
We have version pinning for a reason. It lets churn exist without forcing the effects of it onto other developers. I don't care if a library I use gets updated every week or even every day, I'm not installing every new version when it's released, that's silly. Nobody does that in a real project, that's chaos.
