Thematically speaking? If psionics has a distinct place in the setting that adds to the narrative of the game world, and not just another niche to fill within the overused and crowded bucket of "magical" powers, then sure.
But then it has to offer something unique, not just another "wizard" with a "weird mind-magic" overlay. And that is kinda where traditional D&D systems has trouble making space for it. They always default to make everything possible a "spell". That's essentially the core of their powers and abilities options because it's easy to plug in, endlessly flexible, and has built in controls (level, format, class specificity, etc).
The one that managed to incorporate psionics better was 4th edition. It integrated seamlessly with the core structures, balancing evenly against both player progression and challenge scaling. It felt unique with it's own identity rather than trying to share similar spaces with arcane, divine, or primal classes. Even the classes themselves had distinctive features so they played differently at the same table, but shared just enough similarities to distinguish themselves to be properly classified as 'psionic'.
That said, I did not care for their approach to try to squeeze psionics into the "Far Realm", "madness", and "abberations" buckets of low-hanging fruit. That's the one piece of lore and setting that I couldn't vibe with.
