 Good point and agreed. In that case it's a matter of figuring out the
 originating plugin by the enqueued's script's path, and loading the
 appropriate file from there. There is the use case of premium plugins
 which bundle functionality of their free counterpart and have separate
 domains for translations from the free plugin and premium additions so I
 do believe this should be filterable.

 > Note that with #meta3876 we'd get Jed-formatted JSON files (one JSON
 file per JS file). It would be way easier if we can just pass these files
 to setLocaleData() instead of doing some hacky things server-side to get
 different domains.

 Agreed. I think the ideal implementation would be basically @nerrad his
 function except it can perhaps take a file path directly and simply use
 `get_file_contents` instead of having to decode and then encode the json
 again.

 That just leaves automatically detecting if translation files exist for
 enqueued scripts I think.
