Personally, I'd let it in. And I typically am pretty tight on what goes in or out. But the kind of game I run you can guaran-frikken-tee they wouldn't be getting that bonus for nothing. You want artillery spells with this bonus? Fine. I'm sure your new pit fiend master would be glad to grant them, worm.
But it isn't for everyone's game. This is why I don't advocate saying 'source A, B, or C is in, everything else is out'. More efficient to approve things one by one, for each campaign. If it isn't in the core, ask me before you take it.
