To work the way it was proposed on tweet, I think the real benefit would be of multiple concentrations. If it is so, to simplify its implementation, it would be easier to just incorporate those special points to the power point progression and then rewrite psionic mastery to allow, starting at 11th level, once per day, concentration in up to 9 points worth of powers at once, increasing this use to 2x at level 13, 3x at level 15 and 4x at level 17, and increasing the limit to 11 points at level 15.
If nova damage was really relevant, why most powers have a hard 7 point limit, when the class as a whole already has this same limit, and some random powers work as exceptions? This creates really wonky interactions, as some disciplines simply have "higher power" effects while other similar effects don't.
