Alternatively, if you prefer yarnd to pretty-print all twts nicely, even ones from simpler clients, that’s fine too and you don’t need to change anything. My ¼ -> ¼ thing is nothing more than a minor irritation which probably isn’t worth overthinking.

Yeah I’ve closed the PR, I just wanted to write it up and see what we all thought. Much easier to talk to a concrete spec proposal sometimes. I realised as I was writing it too that it wasn’t really going to achieve much in practise. I think we all agree 👍
