I agree with you. Classic is by far my favorite design but i am fine with it not being universal. I don't ever understand the obsession with extremes.
Take away the trunks its fine. But don't take it away from everywhere. I am all for alternating costumes in comics. Clearly a good chunk of people don't like it. And there's a clear chunk who like it too. Why piss off one section of fans? I say let one arc with the classic and another arc with good alternatives like Reborn. Extreme positions usually don't work.
