Buggy includes non-security bugs, like a flaw in the UI that upstream already corrected in a newer version, or a feature you need that was compiled out by the packager.

In that case, I’d suggest either paying someone to backport the fix and offer it to the distro, or rolling your own repo with your package and a minimal set of dependencies (the more minimal, the better) and live with your almost-distro. The beauty of open source is that you can always work your way out of a situation.
