It's a cultural issue, always feeling the urge to update to the newest possible package for things that are already working fine, without even reading the changelog to see if it's applicable. Cooldowns are only a way to force a bit of patience onto the maintainers... and they work.
That, and package owners updating stuff that needs no updating just to look not stale/unupdated. I can use lisp packages without changes for 15 years fine, but a js one is unmaintained! oh no! Even though it was done 15 years ago, so they add nothing, sometimes a breaking change, to up a version on npm and github and look maintained. And then everything will update.
