I don't see this happening. local state would invalidate many things in the Elm ecosystem like the time travel debugger, all the tutorials, etc. It's not such an easy problem, you have to write a new reconciler that only renders the things that have changed instead of always rendering the entire tree. btw, redux only deal with global state but encourages the use of local (setState based) state whenever it makes sense.
