I have been having very similar thoughts. I'm not saying I think they shouldn't. Like you, I just don't know, and I'm in "wait and see" mode. But the MCU is different. You listed some of the reasons. But I also don't think we should discount the fact that the MCU exists because of Marvel comics, and in my opinion, the history of Marvel comics has had a huge impact on the success of the MCU. Reading comics as a kid, I had my favorite set of go-to books that I regularly read. I didn't have time or money to read everything, but that was okay. But I knew those other characters were out there, doing their own thing, and having their own story arcs in this same, shared universe. When a crossover happened, it was pretty cool and exciting, and it generated an interest in those other books. The huge, multi-book crossovers amplified that even more. That legacy is built into the MCU, and they successfully found a way to subliminally carry it over from the books and make it work in film. For whatever reason, that is very difficult to replicate. That's part of the reason why, for example, the DCEU failed in its attempt to replicate that formula. In theory, it could work for Star Wars as well. We kind of know there is this huge, unexplored universe of potential characters and stories out there. It should work. In theory. But in practice, I'm not sure it will.
