Immersive Capable/WebXR meta tag?

[AdaRoseCannon]

It would be neat if there was a way to describe in the HTML the Immersive capabilities of the web page. It could be used for:

• SEO
• Ambient Badging
• PWA enhancement?
• Archival & Research to know Web page capability trends

1. Does this sound like something that could be worth while?
2. What would you use it for if it was available?
3. Where should it be tag in head, in PWA manifest, http header?

/facetoface Something I'd like to discuss
