I sort of think this except I had a job for several years where we had really good technical writers who would sit with various developer and produce far more accessible writing than I ever have.

It is valuable for my career to be able to write somewhat well but I am hired and earn my salary in other ways, debugging weird technical things; two days experiments, code reading, and maybe gdb and then one small PR and a short email explaining the issue. Write some nice network server to solve a network issue; implement some feature in a maintainable way. Etc. lot of work and mostly the way of thinking about it is a small piece of that work.

The tech writers made a small book that could be handed and/or emailed to people who then integrated with my API with no further interaction between me and them. It was very helpful.
