The other text was merged in # 49\, which points to #19\, which also is unfortunately light on discussion but at least provides some context: Browsers wanted to ability to use con trollers as more traditional gamepads for non-XR content. The group agreed that this was a good idea and the text was added to support that use case .\n>\n>The complication comes from this: Yes\, you can show XR controllers as standard gamepads if the user agent wants to. But can you have them in the gamepads array AND as an XRInputSource on an active session at the sa me time? I'm inclined to say no\, and I think that's what this (admittedly confusing) apparent text contradiction is trying to say.\n>\n>When the te xt says "An XRInputSource's associated Gamepad MAY be exposed via navigato r.getGamepads()" I think it's using "XRInputSource" not necessarily as an actual `XRInputSource` instance attached to an `XRSession` but as a more a bstract "Input source for an XR device that may be exposed as an `XRInputS ource` instance at some point." (Yes\, that's confusing. I blame myself.) It would make sense to me to say that a controller can be exposed as a typ ical gamepad if the UA wants up until an `XRSession` is started. If the co ntroller then shows up as an input source for that session it MUST NOT app ear in the normal gamepad list until the session has ended. That way we av oid getting accidental double-processing of inputs and it's very clear whi ch interfaces developers should be looking to in order to handle XR input. \n>\n>That being said\, this obviously needs some clearer text all around\ , and regardless of my speculating above I think the more important consid eration at this point is what are implementations currently doing and how might existing content break if we make changes here. As such I think this is a great topic for our next meeting.\n\n* [model-element#88 Fresh run a t the introduction section](https://github.com/immersive-web/model-element /pull/88) [requested by zachernuk](https://github.com/immersive-web/model- element/pull/88#issuecomment-2215469193)\n> Re-framed the scope of what a declarative element being managed directly by the user agent actually has the ability to achieve!\n >\n\n* [model-element#89 Expand and revise examp les section](https://github.com/immersive-web/model-element/pull/89) [requ ested by zachernuk](https://github.com/immersive-web/model-element/pull/89 #issuecomment-2215496417)\n> Added the examples already sketched out in th e document and added some more based on a tentative approach to MVP functi onality.\n >\n\n* [hit-test#117 Use of FrozenArray<>s for return types of methods is probably unnecessary](https://github.com/immersive-web/hit-test /issues/117) [requested by toji](https://github.com/immersive-web/hit-test /issues/117#issuecomment-2150866464)\n> I think the intent WAS for this to be an optimization.
