Fullscreen console is also my favorite way of playing roguelikes. (Several years ago I also did other operations (like editing files or ssh) on full screen, but now I use window environment, except for roguelikes, and when I just want to log on for a few minutes on my work computer, where it is faster to log on a console.)
I think they do not want to scare off "ordinary people" and for this reason they make it hard for the user to do scary stuff such as using the console, using it fullscreen (which is probably considered ugly by those not accustomed), performing file operations in a comfortable way, doing any programming or scripting, or playing roguelikes.
