> I don't see what would keep them from implementing this for aux, although since it's unidirectional
No electric circuit is unidirectional. Beyond the pause/play and volume commands that it supports (edit: and mic as mentioned in a sibling comment), Graphene would probably reason it's an easy way to externally read voltage levels and so an unnamed entity can mount side channel attacks with backdoored headphones
