Since they reboot and retcon so often, I don't get why they don't at least give exploring that aspect a shot. We know the reset button can be hit (as it often is) if it doesn't work out.
I'd vastly prefer the Trinity just debuting in the modern age at the same time, and the JSA back on Earth-2. And of course DC is avoiding their original setup that worked much better than any of the subsequent versions. But if Clark's ship is landing in 1941 anyway, and literally everyone else from the Golden Age save Batman is debuting when they originally did, why not cut the bullshit and have the rocket land earlier so he can arrive in 1938? Why does he lose his milestone and miss out on the Golden Age when he was there and the one who started the whole thing, and he has just as much of an in-story reason to be there as Diana?
Supreme proved it can work provided DC and fans give it a chance.
If you mean him arriving in the Golden Age, he could work for George Taylor at the Daily Star. Perry and the Planet wouldn't be around yet.
Do what Supreme did and make Lana Lang (there called Judy Jordan) his Golden Age girlfriend, while Lois Lane/Diana Dane is his modern one (and the endgame). Expand Pete Ross's as a supporting character. The Legion could show up since they time travel. Have him fight, among others, Ultra-Humanite and the original Toyman and Metalo (one "l"). I think there is plenty to do with Superman without Lois and Jimmy in his early career, DC and fans just need to accept that they wouldn't be there from the start. But they'd be there for the age where Superman leads the JL, the age of the main marquee heroes where most of the stories are being told, so that's what really matters.
