Mouse coordinates are useful for quick and rough specification of a line/rectangle by clicking two points in the view port. In some cases roughly specified geometry is sufficient, while additional tuning of the specified line/rectangle by manual editing of the coordinates is desirable.
For instance try to define a render border of 500-by-500 pixels. Mouse operation comes in handy for roughly defining the border of that size, but precisely doing so is hard without manual parameter tweaks. When defining a diagonal line, specifying a start point by a mouse click may be difficult and time to time you might want to slightly move the start point after you finish specifying the end point. I think the difficulty with mouse-based geometry specification is partly due to the lack of real-time feedback of the screen-space mouse coordinates (let me know if I am missing an existing functionality). Even with such a feedback, manual refinement after the initial line/rectangle definition still comes in handy (no so often but) certainly in some cases. Plus, I guess the screen-space coordinate parameters showing up in the redo operation panel wouldn't appear bothering anyway.
