 Replying to [comment:67 swissspidy]:
 > Projects like Jetpack easily have hundreds of translatable strings.
 Passing all the strings will be too much for them, and separating JS
 strings on the fly would have a bigger performance impact than just
 providing a JSON file right from the beginning. The language pack system
 with its update system has been reliable for so long now that I don't see
 any harm in providing separate files.

 How would this work with local development? (And, for that matter, non-
 repository plugins.) Would we still need a dynamic piece for this?
