When software works it just works, and if you don't change it it continues to work. But if you had an issue, its unlikely that it would be fixed or that new features you want would arrive. Unsupported is fine for much software on the world.
Hardware is evolving, and while the core feature set works, it wont keep up. If you personally don't care about those things, that fine, and its a feature for you. But eternal stagnation isn't actually a realistic option.
