I am not defending Apple here but perhaps they intend to make this a public entitlement or even an official API but they are working with Zoom to test it first. We know Apple gives testing priority to certain developers, they mention it at practically every presentation they do. Granted those are usually for NDA’d features for making demo-only apps.
