This is basically just Scribble (docs for Racket). If you have input, I'd venture to guess contributions are more than welcome!
So I would say, contributions do not seem to be welcome on this topic.

It's pretty clear from this that scribble will never support mobile. I can't remember if I pulled the CSS from this change or if I came up with something myself, but making it work slightly better on my phone at least was a pretty small change, not sure if I have it around still or not.
