Demons and Penetration/Concentration

Is there anything stopping Demons from learning the abilities Penetration or Concentration? None of the demons in RoP:I's beastiary have them, so I'm starting to wonder...

Aside from their lack of Patience (it being a virtue*), not that I know of.

*NB! virtue, not Virtue

As Concentration is a General ability it is open to anyone. Penetration needs a virtue to access as an Arcane ability, but I think being a demon covers that very nicely. Both ok imho.

I have been giving my Demons, Jinn, and other Spirits Penetration. I have also considered if the Demon's Obsession Power, or other Sin themed power is similar to the Magi's they would get a sympathetic penetration multiplier in order to make demons' magic a bit more threatening.
