I think it can be, since being petty was Otto's whole thing (He basically wanted to nuke New York because of a pissing contest with Owl that one time), but Otto is a character who can use his brains in varied, smart ways (Master Planner being a popular example) and was still tough to fight, and while for a long time he was Spidey's biggest enemy, he didn't show up that much, so it didn't get old fast, but if a character is meant to be a bigger deal and show up more, then yeah, gotta have more than that to make them more varied, to have a point for them to show up so much, something modern Norman certainly doesn't lack, 'cause while I find him to be overrated, but he's certainly a flexible character.
Oh, Electro was also very petty, although he was more of a semi recurring villain, not really a major threat, so it also worked for him well enough.
