Do be fair, it is also not mentioned to delete the "normal/original" language pack either - but I get your point.
This is how it could look in the future with more languages for an option. You simple click on your preferred flag, like German as in my e. g. The game will switch to this language and always will remember your preferred language due to the config file. But when you feel like to switch to Russian or any other language just click on a different flag and apply the language. No overriding or deletion needed. Buf ofc, you always can add and remove your favorite Klingon, LOTR, Chewbacca, etc. language.

And this is pretty awesome in my opinion.
