 Replying to [comment:35 swissspidy]:
 > Besides that, I'm still tinkering with the patch to find the best way to
 load the translation files. We could load the JSON files in PHP and use
 `wp_add_inline_script` to initialize them or we could also fetch them via
 Ajax (think `wp.i18n.load_textdomain()`).

 That sounds interesting but for v1 we should load them via
 `wp_add_inline_script()`. Loading strings asynchronously sounds
 complicated. :)

 [attachment:20491.5.diff]:
 * It looks like the JS minify task ignores the `@preserve` tag in the file
 header.
 * Is `numberFormat()` compatible with WordPress' license? There is a
 `@license See CREDITS.md` tag but the file doesn't exist.
 * I wonder if we should make `wp.i18n.sprintf()` public or if there should
 be a wrapper instead. Something like `wp.i18n.translate( 'Foo %1$s, %2$s',
 arg1, arg2 )` as an alternative for `wp.i18n.sprintf( wp.i18n.__( 'Foo
 %1$s, %2$s', 'domain' ), arg1, arg2 )`
