I know, but they are usually months or years behind. If a customer tells me that they are working with Language x.y.z I need to install that version, no matter what my distro gives me. And if a project is N versions ahead of the version in my distro, I usually install from either their own PPA or docker image. If I had one euro for every time I read something along the lines of "the version of our software available in Debian is terribly out of date, do not install it, it's full of bugs that we fixed on the last years plus new features. Follow our installation procedure instead."
