While I appreciate the difference between mirroring and emulation, @lemmyvore@feddit.nl might have a point in so far as scrcpy and other options that aren't emulation, may still be part of the reason why no one is making polished emulation options. If a dev can get by with a bunch of physical devices connected and controllev via adb, scrcpy and the like, or a passable emulator in Android Studio, then there's less reason for them to build or contribute to an emulator for their needs, and consequently op (and the rest of us) don't get a shiny open-source emulator.
