Option is already a lang item, so that would t be an issue. I don’t know what the actual underlying reason is, or if it was ever even proposed.

I meant more than it already is, I referenced this: https://stackoverflow.com/a/43339003. I do think it would be neat but it's niche enough to not be worth the non-obvious behavior of boxing with `Option`, e.g. you might forget an `else { ... }` and get complex type errors.
