There are 2 things here to note which explain why.
* Most distros offer multiple desktops. This is true of Debian, Ubuntu, Fedora, openSUSE, Arch, etc.
Point-and-click instructions are limited to only 1 desktop. Shell instructions work on all of them.
* GUI instructions can't be copied and pasted. They must be performed by the user. But most people do not know the difference between buttons and spinners and input boxes. It's very very hard to write specific instructions for people who lack the vocabulary for GUI controls.
