Dominik,

Thanks for the explanation!

I still have a few questions:
What did the "hooking it into Fullscreen API" approach look like in your
mind? and what requirements and use cases it couldn't match?
Do you think we still want a Fullscreen API like, partial mirroring API,
accompanied with the current Presentation API? App-level mirroring seems
still hard with current Presentation API, and some demos require
browsers' private APIs.
