Whether they're included in the latest major distributions is quite irrelevant unless a developer (or indeed, user) is USING the latest major distributions. I imagine (okay, know) that unix-heads can be pretty shy of re-installing their operating system world just to get a small handful of the latest versions of OMG L33T DEPS!!! apps working properly.
As you say, as time approaches infinity the issue tends to zero.
