From the article: "new features for controlling power wheelchairs with Apple Vision Pro"
Someone using this feature will want motion cues as well.
And in your quote: Dwell Control is a feature set to interact with an Apple Vision Pro using only your eyes. Lingering your gaze on a button will press it. An AVP is now more comfortable to use in more situations because of motion cues.
Maybe just rethink your "maybe just" comment...?
