Neither useless nor impossible, but who will bother? There are simply
too few folks with a need for it. It might happen a bit like Unix
did, where some of the commands were programmers at Bell Labs
scratching personal itches because *they* wanted a tool that did that
and could create one.
But while you can arguably do useful work (if you're a programmer, at
least) on a bare bones Unix system with the standard utilities but
*no* third party apps, DOS isn't in the same league. What can you do
with *only* DOS and *no* apps? Not enough.
