Wonder what's the story behind this not being made by the Khronos Group. Especially since, at least according to Wikipedia, it's based on Vladimir Vukićević's work.
The name choice is interesting. If one of the first things in your FAQ is "the name probably made you think this is thing X. it's not", then maybe there was a flaw in your naming process.
I'm talking about WebXR, which is for some reason the name of the standard developed by W3C.
"As such it may seem like WebXR and OpenXR have a relationship like WebGL and OpenGL, where the web API is a near 1:1 mapping of the native API. This is not the case with WebXR and OpenXR, as they are distinct APIs being developed by different standards bodies."
Alright, fine. WebVR predates OpenXR by about 3 years. When WebVR was renamed to WebXR, OpenXR existed in name only, and nobody knew if, once the spec even came out, it would get adopted. It wasn't a well-known name at large by that point, and there was significant concern from the W3C to avoid confusion with creating separate WebVR and WebAR APIs. So, "they should have been careful to avoid confusion with OpenXR" gets it backwards, over-assigning the ownership of "XR"-named things to Khronos.
