Is There a Developer Kit for Hand Tracking?

There just isn't anything that can simulate this because even if you used headset by another brand, it's not going to have all of the features. I feel like as you're explaining this to me, I'm coming around to the idea that has to be some kind of development kit solution. And so it's entirely possible if they're going down that road where initially there is limited developer support in terms of what's possible or at least the broad experience they're hoping from developers are existing experiences.
