I disagree for two reasons:

(1) `line-number-mode' and `column-number-mode' are global modes, that's
why they are on the menu-bar.  Mode lines are merely buffer-local (the
nearest equivalent to "window-local").

(2) When there's no entry on the mode line how do you turn it on?

I could imagine binding left and right mouse clicks to `next-line' and
`previous-line' for the line-number indicator and something similar for
the column-number indicator.
