TL;DR: Good step for the entire market, productization is the harder problem.

I had been formerly involved with Kemtai, which built a fantastic physical therapy/fitness experience (in my biased view) using motion tracking.

If anyone's interested, it is running well and quickly over WebGL on a pretty impressive share of regular phones and laptops across all platforms with WebGL (not just Apple)

My learnings is that the hard part is the productization on top of motion tracking: what constitutes an exercise? What is a "good" performance? How to build the authoring workflow for the many hundreds to low thousands of exercises necessary to reach a typical user base?

In any case, that's awesome news. There are literally billions of people whose condition is going to be better via motion tracking based health and fitness. May it grow there, and quickly!
