As I see it, it's mostly a readability issue; and there's also the
matter of printability: even today, paper is of a finite width!
However, to address Andreas's subsequent question: yes, it would
be possible to allow longer names for scalars and matrices without
having to redo all the printing functions. It would be tricky
though. Perhaps after 1.6.6.
