There are only spells, not psionic and non-psionic ones. Notice the new spells do not have a "psionic" tag and that trait doesn't specify non-psionic spells or psionic spells. That is your distinction, not WotC's.So you can use the psionic die in place of the component for a NON-PSIONIC spell. That's not a component for psionics. It's a bonus ability psionic PCs have that will allow them to forgo a component for that NON-PSIONIC spell, if they CHOOSE.
Edit: Or put another way, if you are optionally using the die to convert a spell into a psionic ability that then has no components, you have not used a component to use the psionic power. The die is not a component, it is a resource. The power does not say you can use the die as a component to replace the components of the spell. It says you use it to make the ability mental and it then has NO components.
What the mechanic is modeling is that if you have greater psionic energy (the psionic die is a measure of psionic energy) you can disregard the material and somatic components. It states that right in the description. FYI, all psionic subclasses in this UA get a psionic die, so it very much is a feature of psionics in this draft.
I'm pretty sure your just trolling me at this point, so I'm out. Thank you for the discussion though - have a great day and stay safe!
