The issue being that not all manpages are created equal. Some only document 2% of the program's functionality, others drone on and on about insignificant features, others are just unclear in their wording. It makes it so that people only consult the manpages when they need to.
That said, reading the manpages for something that you use all the time like ssh is a good idea. (Though if you use zsh, I'll take a bit to go through all of the documentation)
