For any VR devs here, Unity is deprecating their OpenVR plugin and will be removed with 2020.1. Valve will be making their own plugin after that.

>For SteamVR, the change means that responsibility for support of Valve’s platform in Unity now rests solely on Valve. It also may make it more difficult for Valve to work around engine-level bugs or introduce new features that require engine support.
>At the end of the day, however, this probably won’t really mean much to the average SteamVR developer other than the fact that the party responsible for the core OpenVR support in the engine changed.
Also GearVR and Daydream are deprecated for good, not like anyone cares about them.
