It's nearly impossible to do that platform-independently, so most likely the answer here is 'no, it won't be done'.

There's a similar automatic pause/resume thing for embedded emulators on X11 platforms, but it requires synthetic key-presses/releases which are not portable.

The right way to go here would be through the OSD of the emulator (which is able to get informed when it loses/gains focus) and an additional option to enable auto-pause/resume.
