I don't think what you're saying is necessarily true. Browsers for example are very resilient at this point, and seem to handle auto-updates just fine. Worst case scenario you can use a different browser for a couple of hours. The upside is that auto-updating works in most cases and users hardly notice, while you're shipping security fixes straight to them. With developer tools it's different. Your tool stops working and suddenly you cannot work. You often can't just change the tool either, without having to rewrite stuff. For this, it's necessary that versions stay the same until we're ready to upgrade. Same goes for libraries you're using and so on.
