> It's probably because Emacs traditionally displays the line but not the column number in the mode line. The reason for that, in turn, is that updating the column number for each typed character makes Emacs less usable over a slow serial line (like 1200 bit/s).

It is also because displaying the column requires to redraw the mode
line on every move of the point, which is expensive and slows down
redisplay.
