Well the example on removal was “(such as opting out of PvP)”. So yes, optional could still be removal if you can get rid of something from the gameplay. It’d be up to the mods to decide whether such an idea falls within the intended meaning of the rule as to whether to forward the idea. But if the devs rejected it that’s the most plausible reason from that listIs it really a removal if its optional though? There's no benefit in making users do the tutorial multiple times.
