In my opinion it is a good thing. Being able to apply a multitude (almost limitless number) of special affects to the listed set of powers allows you to create abilities and powers that you would never imagine you could create just from reading the list in the book.

In fact a new game, Savage World is trying to take this concept to a new level by offering only 24 powers and then gives guidelines on how the power's "Trappings" affect the power in the GM's setting.
