I think you are right...they either go back to their own times, or they stay in the present. Going back means we would rarely, if ever, see them again since nobody is writing/publishing new stories about the Golden Age. Staying in the present is more likely to create new story opportunities. I would enjoy reading an ongoing about them featuring Courtney and Emiko.
Don’t we already have references to the fact that some of the characters do make it through the present via the future JSA with Judy and Salem?
In new golden age we see adult Judy wearing Jay’s helmet and in JSA red lantern talks about Salem having it out for Khalid.

Words to live by.
If there are numerous characters who appear here despite nothing in the past to indicate their existence, then why should Flip and Famous Bobby be any different?

Just gonna throw this idea out there:
Per Degaton is a grown-up Corky Baxter.

Kinda surprised we haven't seen Secret yet, as we're at the midway point.
Wonder if she's gonna be the island itself?
I know its being ignored for simplicity's sake, but its moments like this, and the whole "everything is canon" take DC is going for, that Batman's, Superman's, and even Dick's eras during the Golden Age. Though, it seems Roy's time is still there (which is a whole other can of worms).
Roy's time could be attributed to his and Ollie's time trip to WW2 era and their experiences with the Seven Soldiers of Victory. Granted, that is still very messy if any details are looked at too closely, but it's enough for me to think that there would be some sort of name recognition at the very least.

That it does. I'm personally for junking any mention of the replacements and going with all Ollie and Roy. It's possible to have some as replacements at different times so Ollie, TNT, and Spider could all have been members at some point, but with DC's historic "continuity" changing on a regular basis, it's likely a solution in 2023 won't be valid for 2025 or even 2024.
