Well you obviously don't know much about mods. Mods are modified existing game files which are taken directly from the game Data directory.
You do extract some resources as XML files that you use to create mods. That is not the same as distributing game files.
Yes and the language package files are nothing but text files where the strings are given the appropriate translation text. It's nothing like sharing actual gameplay files. In the past people used to share their languages packages online and help people edit the registry to use another language but that method is now obsolete. I would rather have a statement of someone who's genuinely suitable to give a comment about that specific scenario.
