The thing that gets me about all the "controversies" surrounding TKJ, quite frankly, is how little an understanding of the workings behind your typical superhero comic people - in many cases, people like Gail "Women in Refrigerators" Simone, who have actually worked in the medium - seem to have.
A superhero is first and foremost an IP and a brand, a name and a likeness - to wit, those of the character on the cover. Its single purpose is to make its parent company's shareholders as much money as possible.
Given that, it's fairly obvious that everything in any of said characters' fictional universe is going to revolve around, and be essentially no more than props to keep interest in, these characters. Secondary characters are no exception, nor can I think of a single logical reason why they should be.
If you have an issue with that model then perhaps you might want to widen your reading horizons. There's plenty of fiction, commercial and otherwise, that doesn't operate under it, really.
