Because they would need to support it. When you run your Windows 10 with four zillion applications and twice the number of drivers, you have a continuous queue to the help desk. Sometimes from reasonable users, sometimes from bozos. Now imagine I come with my favourite Atari 400 and the 10 Gbps driver does not work. It is easy to dream of users being self-managed, but this will not happen, ever.
