Re: [mediacapture-image] Include malicious sites and surveillance cameras in the PTZ explainer (#222)

> User Gesture and Focused Frame (Page Visibility API) might hurt user experience and hamper some use cases, so we might prefer to keep this at the discretion of UA and add a NOTE to the spec. PTZ being a separate permission allows such hooks to the UA to experiment with what works best for their users.

Can you elaborate on your concerns here? To be clear I was assuming that these requirements would apply when permission was requested, not when the capability is used. It seems reasonable to require a user gesture when requesting camera + PTZ. The current specification does not require this for `getUserMedia()` but I have a feeling this is a legacy concession.

Requirements for using an API should be normatively specified. Allowing UA's to vary these requirements hurts interop.
