Efforts to make force-unwrapping more visible by making it more verbose faired poorly in review and are unlikely to make it into the langauge. I like the idea personally, but it looks like it will forever be an idea that lives in user extensions. (Here's the self-documenting one I use, and how it looks in context.)
However, making Never a true bottom type does always seem to get support whenever it comes up. I see @suyashsrijan already linked to the recent discussion. I'd love to see the questions in that thread resolved. (Also, nice trick making ?? handle rhs Never like that.)
