Technically they could already do this as JPEG allows adding arbitrary data to the file after the image data. ZIP files allow arbitrary data BEFORE the image data, therefore a file can be a valid JPEG and ZIP at the same time. So all you need to do is to put the MOV into a ZIP and append that to the image file, done. Live Photos in a single file!

Btw., you can abuse the „unlimited“ „free“ photos storage that comes with Amazon Prime that way.
