I do, MIDI 2.0. It's not because they're not doing it, just that they're doing it at a glacial pace compared to everyone else. They have reasons for this (a complete rewrite of the windows media services APIs and internals) but it's taken years and delays to do something that shipped on Linux over two years ago and on Apple more like 5 (although there were some protocol changes over that time).
