So? It means you will have three different ways to play a psionic character. How many would you need?
I mean, buddy, you really seem to hate psionics, and it doesn't seem to be any kind of well-reasoned argument that's behind it, so I'm not sure how to engage with stuff like this, which looks like weird sniping. There's no psion/psionicist class - that's what I want. It's not really a complicated thing to understand. Right now it's like if we had Arcane Trickster, Eldritch Knight, and something else, and someone was saying "Why can't I play a Wizard?" (let's leave sorcerers out of this for now), and you're like "You can play an AT, or EK, or [subclass 3], you have three ways to play a Wizard, what more to do you want!". As an argument, it's irrational and somewhat laughable.
