[PU4, Powers] What does Cosmic power modifier actually do?

Yes, Powers says that the first +50% portion of any Cosmic modifier is counts as a power modifier, but that's strange. That means that if I buy any of instances of Cosmic listed on pp. 6-9 in PU4 for any of my ability, it automatically becomes one that "originates from primordial energy of cosmic somesuch" because it's now part of Cosmic power. It's not always appropriate if my character concept is a speedster with Enhanced Move (Second Nature) but not "a spawn of Cosmic Elder One" or something like this.

"Raw" advantages are already immune to any power dampers or equivalent Neutralize (including Neutralize (Cosmic)). Levitating psis and beam-shooting supers will be deprived of their abilities (Flight (Psi) and Innate Attack (Super)) in appropriate power dampers, while flying birds and stinging insects won't lose their Flight (Winged) and Innate Attack.

Making an ability usable on any other dimensions, and/or in any body the user occupies is indeed useful, but it's meaningless if dimension travel doesn't exist in the campaign and the same user doesn't have Possesion advantage. To me, charging +50% seems excessive.
