I am.
My issue is that an aberrant mind sorcerer can make a stand-in if you want to translate someone with psychic powers into D&D. But it's not sufficient if you want psionics to be an important part of your campaign on equal terms with arcane, primal, and divine magic, and if you want psionics to be something that's actually studied rather than just something weird mutants happen to have. Then you need to have one or more classes dedicated to it, and make sure it has enough breadth to support multiple builds and subclasses.
In other words: the aberrant mind sorcerer gets you Eleven. A proper psion class gets you Jedi.
Of course psionics shouldn't be Int-based. 2e had them as primarily Wisdom-based, with minor contributions from Intelligence and Constitution.
I could see a wizard/sorcerer split between psychic classes, with the trained psion being Wisdom-based and the weird mutant being Charisma-based.
