Using either Docker or KVM might be the best way to deal with fragle applications or environment requirements. Just take a snapshot before running updates and revert as needed. The problem is that such upstream bugs appear and disappear, but subtle effects might not be detected for weeks or months. There's a lot of value in stabilizing on a specific release and only testing and fixing bugs until you are reasonably sure that everything works right together, like Red Hat and other LTS distro vendors do. An HFT algorithm losing 2% of transactions for several months would be a major issue, and worse things can happen in critical applications in medical, military or heavy industry - it's difficult enough to get software right without constantly changing dependencies. A Docker container pulling dependencies as "whatever was on GitHub last Tuesday" isn't good enough for such applications, although for web applications it might be fine (plenty of people do just that).
