@Daniel, thanks for your questions / comments. We intend to make getAllScreensMedia available for everybody once isolated web apps launch (we are asking to extend the origin trial to already gain insights on the API before isolated web apps launch - see also the "Short term solution until IWAs are available" section in the design doc). This also brings me to the 2nd part of your question: we made significant progress towards isolated web apps (we are mostly code complete and the intent to launch will be submitted within the next 1-3 milestones).
