The original Vive, Vive Wands and Valve Index controllers work fine with the driver removed. The only thing you appear to lose is lighthouse related activities such as turning them on, turning them off or patching firmware wirelessly.
It's likely that Vive Pro / Vive Pro 2 also does not require this driver for any functionality you actually care about to work. It's also likely HTC or Valve could just write a Lighthouse driver for the standard Bluetooth stack to enable the missing functionality for this case, remove the Broadcom chip, and save a few dollars per unit - and then also have an easier time with the FCC, etc. certifications (which are complicated by radios). However, I don't suspect the people reading this are in a position to, you know, care about any of that.
