Support "local" reference space?

[yourdallaness]

Seems a bit weird that only "local-floor" and "bounded-floor" are supported. Any easy way to get around this?

"local" is default and should always be implicitly on the requiredFeatures list, if I'm reading it right. https://www.w3.org/TR/webxr/#feature-dependencies

the concept of the XROrigin is based on the idea of beeing relative to the floor, that's why only reference spaces relative to the floor are supported

Open to discuss this ofc

Happy to close this, it wouldn't solve my use case as "local" is not supported on vision pro. To anyone who stumbles on this in the future: I added hackily added support for "local" ref space only to find out in testing that vision pro doesn't support it and apple likely never will.

Went with copying the negation of XR Camera position to XR Origin on XR session start which amounts to the same thing in practice, ensures XR Camera/user's eye level is at 0,0,0 on session start.
