Distros are great for off-the-shelf software especially if you don't care which version you get too much. When versions matter, you quickly get into dependency-hell. So long-lived software tend to stabilize, and then remain unchanged.

K8s, go and even ruby, tend to change and evolve. It's usually a bad idea to pull such software from distros then, even if available.

The means to get software is simply too different, and it's a non-problem for everyone but completist distro maintainers.
