That doesn't bother me about Supes in the least. What does bother me is that they continue to *act* as though he has an importance that he couldn't, at this point and in this continuity, logically have ever attained. Either make him the first and let him be that important, or make him not be the first and stop acting like he could ever be that important, either way I'm fine, but make up your damn minds about it, that's all I ask, because you can't have it both ways.
(Actually the reason I didn't include him in my silliness at the end there is because he actually still does have some pretty decent interstellar recognition and history of heroism, and this arc is really just Diana catching up.)
