alvestrand has just created a new issue for 
https://github.com/w3c/mediacapture-image:

== Discussion of "zoom" does not consider mechanical zoom timing ==
With non-electronic zoom, moving from one zoom setting to another 
takes time (seconds).

This specification should say how this is considered.
Options include:

- The desired zoom is what's returned in getPhotoCapabilities. The 
camera does what it wants.
- getPhotoCapabilities returns the current zoom. The user has to poll 
getPhotoCapabilities until the camera's zoom is at the desired point 
(and keep track of what the desired point is).
- setOptions() doesn't resolve its promise until the correct zoom has 
been reached

Either is viable, but which one is intended has to be specified.
