"The popup is anchored to the extension icon, which might be in overflow or not even exist, in which case it is anchored to the Wrench menu. That kind of anchoring would make the message in the popup to appear to be from the Chrome browser (since it points to the chrome UI) and would present a vector for tricking users into thinking the message is from a trusted source.
Since this is not safe to allow all extensions to do we'd need a lot better reasoning than "I'd like to use this in my extension" before allowing widespread use of this API."
"While the Philips Hue system is based on open technologies we are not able to ensure all products from other brands are tested and fully interoperable with all of our software updates. For guaranteed compatibility you need to use Philips Hue or certified Friends of Hue products."
After all, it'd just be downright unthinkable that any non-Philips lightbulb should be compatible with our light sockets, that any brand of plug should fit into our wall sockets, or that non-Google-branded plug-in should be able to use a web browser's APIs... I mean, goodness, next we'll be thinking that the term "plug-in API" suggests its supposed to allow things that other people created to interoperate...
Nobody other than Google (or your OEM) is allowed to build complete screen casting apps on Android. All third party solutions require you to output your audio through your speaker and capture it with your microphone, which is much worse quality, single-channel, and makes sound (I want to hear my device audio through the speakers of the device I'm casting it to).
It makes no sense, especially when any device on your network can emulate being a Miracast receiver and get access to the same audio data that you aren't allowed to access on your own device. In fact, Windows 10 insider preview currently includes a Miracast emulator just for this purpose of Android screen sharing.
