Unfortunately this is I think of one of the D&D design team's foibles. They consistently do a few weird things - I've mentioned that they wildly overvalue natural weapons and natural armour, like to a bananas degree. It's inexplicable. In almost every case they make them a terrible idea, and objectively vastly worse than say, having Elven Weapon Proficiencies or the Mountain Dwarf deal with okay weapons and medium armour, yet they value them as if they were the same as, or better than that. I have no idea what sort of games they're playing, but in thirty years of D&D, the only "natural weapons" using characters I've seen have have been either gimmick characters, where it wasn't mechanically advantageous, just cool, or weird exploits (like where some race got to retain a claw/claw/bite routine or whatever), and the latter just isn't a thing in 5E.
And I think likewise they overvalue trying to make people using full V/S/M components, even though, realistically, 95% of the time, it doesn't even matter, and the other 5% it's either costly components (just adjust those spells or take them off the list) or casting from steatlh - and psionics should be good at being cast from stealth. That's part of it's "thing". So I think they'll mess it up if they try to go the "spell" route.
