This just enshrines what is already the de facto situation both in RL and in Atlasia.
True, and I understand what you mean here. However, the reason why I decided to write this bill was because I don't want an "Official Language Act" to show up to the floor with a list of a small amount of languages (or Dave forbid just English) that would be recognized as official. I've already seen it happen before during an earlier parliamentary term of mine, and I wouldn't be surprised if this has happened other times in different regions. Putting this amendment into place would prevent a bill like that from showing up in the future.
Instead most states will enshrine, or continue to enforce their existing official language laws, which establish English as the sole official language.
