True enough. Standard Lisp defines () as NIL, but its CAR and CDR are
illegal. I don't see the conversion to () as a great effort, mainly just
a matter of finding cases of 'NIL. Since I don't have an ideological axe to
grind, I see the issue as the cost of converting old code vs. the cost to
new implementations of overloading NIL.
