I don’t think that does an actual rewite point. A lot of the localisation features were done using file explorer. You can even “localise” folders yourself using custom desktop.ini files. But those changes only showed in file explorer.

Now email! In exchange the standard folders such as inbox are localised, but don’t have a fixed alias. So if doing administration you need to know the language of a mailbox to know the name of say the Calendar folder, so you can update permissions.

Winamp dumping a bunch or proprietary information on GitHub is a good example of this.
