I did say "At my table" and "YMMV"
They attack as maces, I wouldn't object to the user punching locks off a gate, crushing a rock with it, or systematically smashing a door apart either. . .as if their hands were maces.
Which makes the attacks, IMO, not "merely hands". It's magic after all.
The only PC I've ever allowed to have it as a natural talent, had prosthetic hands from the lay healer list, to explain how that made any sense as a natural course of things, though I guess you could use it as something like "I bathed my hands in the mystic fire" ala "Iron Fist" from the Marvel Comic.
As I said though, merely my opinions, YMMV.
