Having the ability to go and fix or improve an open-source tool is a lot better than the alternative of having some half-baked "official" implementation that will never get fixed. For example, If vrchat provided a way to swap out the IK calculations in-game, I bet we would have vastly improved IK for full body by now without any rig hacks. Or for example a camera whose buttons aren't impossible to hit in game.
