I have an IME for Indic languages that I currently distribute outside of the Mac App Store because it does not seem to be supported. IMEs needs to be installed under /Library/Input Methods/ which I believe is not allowed for App Store apps. I could distribute it as an embedded helper app within my larger distribution app that I then install on start up - but I believe even that is not allowed. Is there a sanctioned way to distribute IMEs via the Mac App Store? The iOS store has support which I was able to use effectively.
