For all intents and purposes yes. There's maybe a couple of minor additions 
from the spec that could be added to the explainer, but I don't think 
anything represents a critical lack in the explainer or anything like that.

I've asked this question before and never gotten a satisfactory answer, but 
the chromestatus tool does not seem to have a spot to put a TAG review 
entry, just the questions regarding it. It looks like there have been minor 
additions, namely the `semanticLabel` attribute as well as the 
`initiateRoomCapture` method. It is worth noting however that these 
features are also launched in the Meta Quest browser already, so I think it 
unlikely that any TAG feedback would reasonably be able to be addressed 
without breaking existing experiences.

loose representation of the user's room/house. Is this new information or 
is this already available to the site via other APIs? I think this is gated 
behind a permission, but I wonder whether the implications of this are 
captured in the permission text for the user to understand.

The privacy team has approved this launch and previously reviewed the 
permission that this is under. As noted on the Privacy gate on the 
Chromestatus entry, similar data is exposed by both the hit-test and 
depth-sensing WebXR APIs, all of which require the same permission prompt.


That great! Do you know what the permission text says? Or do you know where 
I might find that?

Thanks,
Vlad

*Specification*
https://immersive-web.github.io/plane-detection 

*Summary*
The WebXR Plane Detection API allows sites to retrieve the set of planes 
detected in the user's environment. This is both less work for developers 
and more powerful than using the depth-sensing WebXR feature as planes such 
as walls that are occluded by objects can still be fully represented if the 
system is aware of the boundaries of the wall. (Whereas a depth map would 
show the wall, but it would be broken up by any objects in front of the 
wall, potentially obscuring the full scope of the wall). Further, semantic 
labeling information is exposed where the device is aware of such labels 
and they fit into predefined categories, allowing better knowledge about 
the world.

*Gecko*: Defer (https://github.com/mozilla/standards-positions/issues/1346) 
Presumptive 
Defer due to that being the state of all other WebXR positions due to 
current lack of support/development.

*WebKit*: No signal (https://github.com/WebKit/standards-positions/

*WebView application risks*

Does this intent deprecate or change behavior of existing APIs, such that 
it has potentially high risk for Android WebView-based applications? 
*No information provided* 


*Debuggability*
*No information provided* 

*Will this feature be supported on all six Blink platforms (Windows, Mac, 
Linux, ChromeOS, Android, and Android WebView)?*
No 
WebXR itself is only support on Android and Windows, and not on Android 
WebView. This will be supported on all platforms, but primary usage is 
expected to be on Android.

Open questions about a feature may be a source of future web compat or 
interop issues. Please list open issues (e.g. links to known github issues 
in the project for the feature specification) whose resolution may 
introduce web compat/interop risk (e.g., changing to naming or structure of 
the API in a non-backward-compatible way).
