They've done it to a degree but only for graphics drivers, Windows is (AFAIK) unique amongst the major OSes in that it can nearly always recover from a GPU driver or hardware crash without having to reboot. It makes sense that they would focus on that since graphics drivers are by far the most complex ones on most systems and there are only 3 vendors to coordinate API changes with, but it would be nice if they broadened it to other drivers over time.
