Comment (by swissspidy):

 Pressure's on I guess :-)

 Just noticed that `add_action( 'change_local', 'create_initial_taxonomies'
 );` needs to be `add_action( 'change_locale', 'create_initial_taxonomies'
 );` in the latest patch. I think the impact of that approach is
 neglectable as it's reduced to a minimum.

 I opened #38218 for suggesting a `WP_Post_Type_Labels` class though as it
 would be more maintainable.

 Anyway, it's only a problem when doing something like switching the locale
 for the admin bar on the front end.

 > 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.

 Happy to provide one. Post type labels should be irrelevant for that, so
 it should be easy.
