I'm not asking people to will better stories to exist. I'm asking if the mob villains are still currently useful to Superman stories, and I'm only getting people's desires for what they want to see done. Which is interesting, but the actual answer to the question seems to be - no, not really. They're not useful villains and haven't been so in a long time - writers just aren't interested in them, except Bendis with the Invisible Mafia, and that went nowhere. So I guess you're right, there's nothing more really to do but talk about how we wish these characters would be used.
