In many cases though, it means "the default plotting area". For example
the epslatex terminal now has a default of "5 x 3.5 inches". It is quite
conceivable to need an epslatex plot that is larger than this.

Again, using the epslatex terminal as an example: The default size is
based on a typical page width, and a reasonable aspext ratio. Personally I
prefer a slightly taller plot, (because I tend to put the key below) and
my page width isn't exactly 5 inches, so I have:

set size (345.0/72.27)/5.0, 4.0/3.5;

in all my gnuplot files. Secondly however when I use multiplot, I often
want two plots one above the other but keeping the total width to be the
page width, so you then need a:

set size 1,2;

This seems perfectly reasonable, and as far as I can tell works.
Basically your argument only makes sense if each terminal allows an
explicit size argument in the term options. Then the "set size" option
simply allows you to scale the plot within those bounds.
