Nothing inherently, but it’s a rolling release, so the further away from the latest versions you are, the more likely something is going to prevent you from updating. Arch is the same way, but Steam OS is based on Arch snapshots, not a rolling release.
You kinda have to watch after rolling releases pretty constantly in order to keep them up to date and make sure they don’t get left behind.
That does make sense considering every other developed country has free healthcare and literally 100% of their young men spend every waking hour playing video games.
