Mechanic implications of the Psionics tag?

Quite a few monsters have the Innate Spellcasting trait. Some of them, such as the Gith (MM) and the Neothelid (VGtM) have a trait called Innate Spellcasting (Psionics) instead.

I cannot recall having seen any mechanic referencing the fact whether or not someone is a psionic. So my question is: Does the Psionics tag on Innate Spellcasting have mechanic implications?
