I did put the numbers because the OP said this
docs have significant download size rustc and rustlib have significant download size, not the docs... thought
Thought having SSD that means almost nothing ...
N1, I was thinking in downloading them as md files (the download size would be less than HTML I think) then converting them to html would be best in this call, thought with the current HTML download perhaps it is not possible.
Maybe when installing, updating or something, there could be a message you have this opt-in and opt out features: doc.
So the people know that there are or are not docs installed. (Well, for starters, I didnt even know I did have the docs installed or that I can access them trought that command).
Another thing I will like to know if there is no doc installed, what will do
rustup doc do?
