Haven't tried that, but I think adding this from tooling will always lead to friction: "smart comments" are annoying to write.

I understand your point and it's valid. I think RBS is an interesting attempt at typed Ruby while also keeping it backwards compatible. I do however believe that having it as an separate file is not the right solution, it adds more load to the developer and ruins the joy of Ruby

RBS-inline is an interesting attempt at solving it!
