well the correct theory will have to explain what we actually observe, which is going to limit the nature of what these theories can be. I'm not sure if you have an example of something that should be accepted when it's currently not, but usually that's the case when something is clearly broken with regards to basic facts we already know to be true.

My problem with how the physics community is having this discussion is actually the converse of what you are suggesting: None of the existing theories explain every observation we have, and yet we are sticking to the same general frameworks that don't work.
