There has been some controversy in the BattleBit community over the fact that they will implement an anti-cheat that may stop Linux users from playing the game.
Luckily, the developers have confirmed that they will use a new version of the FaceIT anticheat that will still allow Linux/Steam Deck users to keep playing. They will be the first game to implement this feature.
Think this is the most important question on this issue I don’t think it will be just user space.
