The recent update removed the ability to use a headset to play in VR while also using any alternative to handheld motion controls like Keyboard and mouse, gamepad or DS4 controller, or any other accessibility hardware that someone might need to play a game.
Just because someone uses a VR Headset does not mean they can utilize or manipulate motion controllers. Many people who do not have fully functioning hands or arms enjoy playing in VR but cannot use the motion controllers that come with headsets. They need to be able to use alternative hardware. Currently, this functionality has been removed from VR Chat.
VR games and gaming in general should not be off-limits for disabled people. If anything they should be working on becoming more accessible as VR games present a unique opportunity for disabled people to inhabit a world and body outside their own.
