Comment:

 #29783 is landed so this issue needs to be resolved.

 [attachment:26511.7.diff] looks like it has enough abstraction to allow
 core and plugins to run extra actions when a locale is switched. I'm
 currently not sure what impact calling
 `create_initial_post_types()`/`create_initial_taxonomies()` multiple times
 has, this needs some research (and tests).

 [attachment:WP_Post_Type_Labels.diff] should be in its own ticket to
 gather more feedback.

 The main use case for this function in core will be to send emails in the
 language of the site or a user. We'd need a patch for that.
