I guess this is more okay when the dated versions are not exposed publicly but are backing services, but in general it might be a question of time until some CVE puts you at risk or there's a bug that will never be fixed.

I like the idea of having "feature complete" software that you can use from now until the end of time (or at least the end of whatever product you're working on), I just don't think this is always feasible with the way we develop software.
