Good point. Strong promotion is only useful when the piece survives, especially when any capturer would derive new rights from it. Similarly it sometimes pays to 'promote' to an inferior piece, because that would force the recapturer to demote even more, possibly deterring the recapture altogether.
So I guess that making the Elephant immune to the contageon provides an interesting new twist to the tactics in this game, even apart from the promotion piece being royal.
