Rust-based OS or Redox for mobile/TV?

So I've been thinking lately, amidst the frustration of my Android-based "smart" TV having crashing, slow apps and my phone not fairing much better, are there any plans to make or any plans for Redox to spinoff to mobile devices? It would be nice to use apps like Youtube that aren't clunky like Android's Java architecture nor corporately dictative like iOS's ecosystem. I understand there exists Firefox OS, but I don't believe Mozilla, though having launched Rust, built FFOS with it.

I've nowhere near the knowledge to code something as ambitious as a mobile OS, but this is food for thought. With Rust's drill sergeant-like stance on memory safety/data races/etc, such an OS would probably be more efficient and faster than even iOS.
