I feel like once you get into the nuances of it, it's very different. The Titans are a few years younger than what they used to be, like 27?, that's widely different from being in your early 20s, which is widely different from being 16 and under. YJ is no longer direct sidekicks like they used to be like the TT, yet don't have a history of major enemies like Deathstroke and Trigon to carry them into their own space. It gives every reason to leave them where they are I just think there's potential in having those young adult heroes that aren't sidekicks, but aren't defined by a long history and giving them that agency they need. The Titans became a lot more than sidekicks during the NTT-era, it wasn't overnight but it happened. I feel like the second major set of sidekicks deserve similar treatment, rather than just being weirdly and oddly sidelined while sharing codenames they no longer fit.
Once you boil down certain groups into small similarities they all become derivative, which just limits storytelling in the long run.
