Still no native hand tracking for PCVR

I hate to make a new discussion over this topic but at this point meta should be thinking about a port of this in some way. I know developers can send the data over but actually using it for any gameplay outside of a unity development environment is impossible. 
I've heard rumors of 3rd party apps that can do something similar to meta link via the cable and such but that doesn't sound safe.
I enjoy my PCVR experience and all, but losing a large functionality of the headset all because I want to use my link cable so my graphics don't look terrible. (my headset isn't close to the router, so it doesn't have a good connection, and using my computer as a hotspot doesn't boost the quality of the picture. Something like Steam Link or Virtual Desktop[why is this expensive?] is out of the question.)

I understand that meta may not think of their headset as being used as a pc extension but so many people do it already, why not add a bit of functionality to the app you seem to neglect? (the wrist watch is STILL broken). You already have the ability for the data to be sent over so why is Unity the only thing that's allowed to read it? OpenXR can read that data just fine, steam link can understand my hand movements... but on pc steam just... doesn't get a lick of anything? even with developer mode?
There's handfuls upon handfuls of VR games that support hand tracking nowadays, VRChat especially can handle it so I know it's something I can do... So why is the link cable not allowed to use it?
