FWIW, I see a lot of codebases at work (I maintain a large org-wide monorepo), and you'd be surprised at how daunting real world codebases can get. I agree that it's relatively easier to keep a codebase clean when the number of owners is small, but conversely, from my experience, when a codebase has multiple owners, keeping things organized can definitely be a challenge (in some cases I've seen, multiple teams owning overlapping sets of the codebase...) I've seen codebases with messy redux and codebases with messy non-redux architectures, and conversely also clean codebases with both types of architecture. There really is no silver bullet technology. The "you can write cobol in any language" thing is always going to be a looming plague.
