I doubt you’re the only user of the Ruby documentation though. I’m not a (frequent) Ruby user, but I routinely check the Go documentation, the MDN, the Python documentation, and several other language documentations on mobile. Because sometimes I will think of something while I’m walking my dog, or while I’m in my couch, or before sleeping, or at any other moment. Mobile UX is exactly as important as desktop UX. And for a text only website (ie. not a web app) you don’t even need to spend time to make it work, it’s almost the default behavior. You have to go out of your way to make a text website that doesn’t render well on mobile.
