I do like sketching those up, but in an ultra-simplistic way (literally just a word/label and some arrows). Paper sort of extends my working memory, so I use it as a temporary storage to think through something that’s getting too big to hold in my mind. But it is so vague that coming back to it later, or someone else taking a look might not benefit anything.
