While I think this helps, Twitter has their 'lists' feature that effectively allows you to choose what timeline you want to view at any point; the only difference with your post is that it's not forced upon you, and perhaps you envision platform uses some ML model to classify posts from people you never follow. As it stands, people don't like the friction that comes with needing to hand-pick people to put into different twitter lists, so the feature is largely unused.
