Now, whose Maia was Radagast/Aiwendil? Wasn't he Yavanna's (as I seem to remember)?
Were the Istari required to stay celibatary? Probably yes, but how do we know that Radagast (who is described as a failure in almost every other respect) staid true to his orders?
So maybe Beorn's shape-shifting ability was not something learned from Radagast, but inherited from him? And if the fateful mating had taken place far enough back in time (say, a couple of centuries), Beorn wouldn't remember him as his ancestor, but just as a wizard he'd met once or twice upon a time...
