Thank you for the very quick feedback!
We are targeting OT for M92-M94. Because the M92 cut is very close, I am trying to concentrate my efforts on implementation. After that, I plan the following:
a. Present this in the 2021-05-25 W3C WebRTC WG meeting.
b. Either post a full proposal to this Github repo
or create a WICG repo for it.
c. Apply for TAG review well ahead of intent-to-ship.
d. After a while, intent-to-ship.
getDisplayMedia is not currently fully supported on Android, so to reduce scope for the initial implementation, I am not targeting Android either. There's nothing preventing us from expanding scope later on.
I hope these answers are sufficient and experimentation can be approved? :-)
