Aunt May to Peter: "You're not Superman, you know."
What I've always wondered was: was that a reference to Big Blue as a comic character in the Spiderverse, or is Supes alive and well, doin' his superhero thing in Metropolis (just like with the first Superman/Spiderman crossover)?
Shinier than a speeding bullet.
I'd say the former.
Superman's part of the lexicon. Not unusual to see him referenced in pop culture. Just last night i saw a Supes shirt in Big Bang Theory, and watching wrestling this morning witnessed not one, but two Superman punches.
The fact that a Spidey movie could use Superman in conversation was just a wink and a nod to a classic character.
I agree with almost everything the OP said except for the part about Kal-El/Clark ALMOST giving up his powers. He DID give his powers up for a short time. Not almost. I seriously doubt that trucker dude could've beat the crap out of him if he had still had his powers. Instead he probably would've broken his hand sooner than he actually did at the end of the movie when Clark had his powers back.
