I've seen the struggle with not upgrading frameworks and staying on an old version. Usually the cost/risk for upgrading is perceived much higher than it actually is. And the cost/risk of technical debt is mostly ignored. I've seen this issue so often: "we can't use this external component, because we would need to upgrade the framework. Let's just work around it, it will only take 2 days (and 50 more days to maintain it over a decade)"
