I wouldn't count on Apple to allow anything... However, however rclone already runs on ARM. I tried to get it to compile on libTerm and I could not. Maybe with the confluence of MacOS and iOS architectures in the coming months/years this will become easier?
Someone has already got it running on iOS though because cryptCloudViewer is using it.
In other words, why not try to get this running an Apple-ARM rather than hope Apple relaxes their stance on emulators which, to be honest, is probably not happening.
