Backporting is a legitimate choice, and could be the correct one. But it can also a form of adding tech debt. You save a lot of time. In mature codebases where you're never going to do a major-version bump of a core lib it makes sense to backport. As a counterexample, in Javascript land no one wants to support older versions and you'll very quickly fall behind. If you're lucky they'll leave the docs for a few previous versions online, but good luck getting any community support. In these situations you lose most of the advantages of using open-source.
