I wouldn't call it pretty well, not quite yet. The Monado driver has come a long way, but doing anything useful with it still has too much legwork involved for the majority of WMR users, not including the switch to Linux. Although since the announcement, work on WMR-specific stuff seems to have sped up, so hopefully the situation improves.

I also recall seeing a working demo of hand tracking for WMR (maybe just the G2?), so that's neat.
