    1. If you use the mouse to select text, then having the region size always
    visisble (when active) means not having to use `M-=': double-click + click,
    or drag a region - you see how big it is as you drag.

In a case like this, if you have seen the region all the time
you were dragging it, why is it useful to see the size?

    2. In transient mark mode, when you use `C-SPC' the region becomes active,
    even though it is empty. This mode-line indicator shows you that the region
    is active even when you can't see it. When a command (e.g. query-replace)
    limits itself to the region, this helps you avoid the exercise of figuring
    out that you are acting on an empty region.

That is logical, but how often does such a problem occur?  The first
thing an Emac suser will do when something seems broken is type C-g,
and that will deactivate the mark.
