Comment (by rmccue):

 Re:
 > I'm wondering whether to abstract the logic into a reusable function
 which both usages call rather than requiring any logic changes to be made
 in two places.

 I think that makes sense, ''but'' we run into a problem here in that
 there's no good name for the function. We have:

 * `get_available_languages` - Get list of language codes based on the .mo
 files.
 * `wp_get_installed_translations` - Get list of language file data based
 on .mo file headers.
 * `wp_get_available_translations` - Get list of language data based on API
 response.

 None of the existing ones can be used authoritatively, and none of the
 return formats match each other. I can't think of a good name for a new
 function, this is a bit of a mess really.
