Having a Stan Lee cameo in CA:TFA, isn't giving him credit for creating the character. It's giving him credit for what he's done. And that credit doesn't have to be character specific.

I'm aware of the movies he has and hasn't cameoed in. But you don't have to put a blanket rule on it, saying that if he didn't create the character, he shouldn't cameo. The other examples you provided is further proof, that his cameos don't have to be about having created the character.

Like I said, you're thinking about it too much. Anyway, provided the set isn't too far away (I'm pretty sure they're shooting in London) for Guardians, I'm betting he'll cameo in that too.
