humm, I wonder why it seems like that's a thing, they're separately tracked. 
Camera based fbt solutions exist too and you can technically pipe any of the fbt wetsuits into vrchat as well, it's just a bit convoluted. 
Vive trackers persist as basically the only option because they're not TOOOOO expensive, but truth be told they SUCK and someone needs to give them some competition. Fully wireless, base-station free vr is entirely possible with cameras, someone just needs to stick them on a tracker thing.

As in life, there will always be unambitious lazy people satisfied with achieving nothing more than being comfortable for a few hours.
