I argue there is no such thing, and never will be. No option will appease the whole psionics fandom, because as long as it falls short of being perfect for them, they have every reason to fight for making it so.
The only way to get psionics is to actually publish something, despite it not achieving 70%+ approval. Because as long as what you've made is pretty good, then the psi-fandom is no longer given the option of the hypothetical perfect. They must give the thing they've gotten an actual shake. Some will learn to like it; others will never change. But you'll only even potentially be able to clear that 70%+ hurdle once you've laid down the law and said, "No, this IS how psionics will be in 5e."
Unless and until that happens, you'll always be able to find 31%+ of psi-fans willing and ready to tear down whatever was proposed, because it isn't their specific vision of psionics.
