This has been my thinking since the show started. Nothing has convinced me otherwise. I do believe Jordan was the original Jon, the son they planned for but something made them add a second son and switch the names around. Maybe they weren't sure how folks would take to the anxiety plot or someone wanted to play on the alien/human dichotomy around Clark and his two fathers, regardless, it's no excuse for how they've handled Jon since. That's where my frustration with Jon lies, not on the powers even though I wished he had them, the only problem here is how to develop what's essentially a perfect son of Superman character-wise. Everyone on this show is struggling with something, a flaw in their character, including the title leads, Jon basically has no flaws and giving him powers this soon would have made him a flawless Superboy/man and that'n not necessarily the point of this show. There must always be a build up towards something, character growth, positive or negative for viewers to root for. As it stands, many are rooting for him because he has no powers and has been "in desperate need for a win". All I want is a character arc for Jon, powers or not. The thing I do not want is to put the boys in competition with one another, in any shape or form. Putting Jordan on the football team was a mistake that should never have been written. I am hopeful for next season that things will improve for Jon in terms of the writing. No more Cushings getting better writing than Jon Kent, despite having less screen time than the son of Superman.
Derek burnt himself through heat vision after Clark chased him down. I feel the same about re: the boys.
