I'm still interested in what specific weird fantasy psionics you are thinking of. Different interpretations are going to suggest different game design implementations. And much like Vancian magic, any particular choice is going to leave some folks disappointed.Psionics may have been inspired by a single author but fantasy characters with psychic mystical powers was not. However, “psionics” has become much a shorthand term for various psychic power tropes. These were very much a part of weird fantasy.
It seems like most people who want D&D psionics want a new version of traditional D&D psionics. But that has been so convoluted between editions, it is likely impossible to make anyone happy.
