I've thought the same, as I usually don't unlock a lot of powers and so don't get much power-related charms. Also I don't think I got any during my Flesh and Steel run.

EDIT: I'll check my own playthroughs to see if it's accurate. I also have a feeling the appearance of corrupted traits in crafting works the same.
