Comment (by jrf):

 I foresee problems due to this commit.

 There are thousands of (commercial) themes hosted elsewhere and the
 chances that some of these will use the same text-domain as a theme hosted
 on wordpress.org are quite large.

 Similarly, lots of plugins have a free (hosted on wordpress.org) version
 and a commercial version hosted elsewhere often using the same text-

 Loading translations downloaded from translate.wordpress.org first,
 disregarding the load location preference of the theme/plugin author, will
 in that case result in:
 - for the theme example: text strings from another theme with the same
 name being loaded
 - for the plugin example: only the text strings for the free version being

 Both would break localization for the affected themes/plugins.

 I realize that theme/plugin authors can still filter the file path with
 the `load_textdomain_mofile` filter to overrule the location, but the net
 effect in that case would be that any potential additional translations in
 `wp-content/languages` would be disregarded completely.

 Similarly, they could `unload_textdomain()` an incorrectly loaded text-
 domain from `languages` and re-load the correct file using a direct call
 to `load_textdomain()`, but again, this seems like a work-around which
 would be needed because this commit breaks existing and expected
