I appreciate what you're saying, but your seem to not be addressing the point of the post: you could reduce risk by moving to rolling upgrades. A year of changes is a big change, smaller updates are not. There's also a huge risk in stasis.

Not that it's relevant, but to respond to your first point: you know people who roll their browser, and a few Linux distros roll their release too. I've heard of some startups who use a Fedora rather than CentOS for that reason.
