At the same time, the MCU Phase 1 was like this too. Sure, as comic book fans we just knew that they were going to be building towards an Avengers film eventually, but all of the films didn't really connect at first. We got a few hints at something more, but that was in mid/end credits scene and not in the films themselves. Then afterward, with the leadup to Age of Ultron, all of the films seemed to be once again stand alone films with little to nothing in the films about what they were building up to until later when they were closer to Avengers 2.
The same build-up that happened in the early days of the MCU is happening here, the only difference is that they're essentially starting over, almost from scratch. During the first few Phases leading up to Infinity War and Endgame, there were breadcrumbs and subtle hints that gave us an idea of what they were building up to. But now that that's all done, they're laying down the foundation for the next major story arc of the MCU that will culminate in the next Avengers movie. Since Endgame, we've only had a few movies from previously established characters and they've all only had one each the rest were new characters like the Eternals and Shang Chi so it's a little much to expect a whole lot so soon.
