Tbh that’s not too dissimilar to how the golden/silver age comics worked. Clark was originally Superboy helping people around Smallville.
Idk if people actually new but I think it would be hilarious if they did and were just like “yep, we totally don’t know who superboy is, just sending flowers over to the Kents for fun.”
Starting to think a cooler headcanon for Clark’s upbringing might just be that the entire town of Smallville collectively decided to just go with it and accept that Martha and John's kid has superpowers, but we don't talk about it.
Someone's tractor gets stuck and nothing can get it out? "Be a dear and run down to the Kents, would you? Ask for Clark?"
"Why Clark, we need a machine--"
"Run along now."
Or if he kicks too hard and the football vanishes into the upper stratosphere, no it didn't, we all collectively saw it land over there *vague hand movements*
