That power sure seems worth it as a safety net to redo power and feat selections within 10 minutes (!), provided you want to pay the minor XP cost.
You are correct... the problem is, one's 1st level Power choices are rather far back in one's history. So it's a lot of XP to rid yourself of a stinker.
Again, it would be nice if they could change powers like a Sorcerer changes spells, not by spending XP.
(Also, Psychic Reformation may be banned IMC, depending on how much abuse I can get out of it in my friend's campaign...)
