This is kind of what they've done with the Ethereum 2.0, "The Merge," change that they're working on now. They're splitting the consensus and the execution layers, in part to reduce complexity. I think the crux of the issue is that new fundamental components that are tightly coupled are added without putting in additional work to decouple and simplify the whole project.
