Maybe in this particular mode, but it isn't always true.

And I don't really understand what will such a variable solve.  If
some Lisp program can use a value of a variable, it can also call a
function and use its return value, no?

(In any case, we cannot provide a simple variable, because the value
depends on the window -- if the same buffer is displayed in several
windows, the value could be different in each one of those windows.)
