The PSVR2 turned out not to actually use VirtualLink, just more-or-less standard DisplayPort + USB 3 + USB PD over USB-C. Most of the compatibility issues seem to be from it requiring parts of the spec that aren't widely implemented at the same time, like 12V support and display compression. The main open question is how to actually switch it into VR mode so that it's possible to send a stereo image instead of 2D virtual cinema mode, and I don't think anyone is quite sure whether this helps with that at the moment.
