Interoperability and compatibility - browser vendors & web developers support for DOM Overlay

[klausw]

I'm currently preparing to send out an Intent to Ship for WebXR DOM Overlays Module so I'd like to poll for other vendors' support for the module. @raviramachandra, @Manishearth, @thetuvix, @grorg, @kearwood and others - can you share your opinion please?

There's a currently an open issue (#15) about integration with Fullscreen API, I'm working on a PR to address this. (Unless I'm misunderstanding it, I think this is just a matter of clarifications and I'm not expecting API-level changes as a result of this.)

Web developers' opinion about this module is also welcome!

This work is very welcome and the spec is a very nice starting point. Using the 2D DOM in immersive mode has been one of the most requested features by A-Frame devs. Easy ways to build HUDs, instructions, setting menus or Youtube embeds are in high demand and the DOM Overlay seems to happily cover those. Looking forward to integrating in A-Frame.
