I think that if people are not good enough to complete the modes necessary to get the pictures / outfits, it makes sense to put in a code so that they can see them, if they want to. I personally play the game for the challenge, so I haven't used cheats, and I'm trying to get SS rankings with both characters, even though you only get the reward once (if you get SS on one difficulty with Dante, you get the reward, but if you then do it with Vergil, you get nothing). But for people who don't play the game for the same reasons, what's the problem with them entering a cheat? It's not like they're pretending that they did it - that would be dumb!
