Could you elaborate and tell us about a few such formulas
and in which articles they are ?
Every formula that has lots of nested parentheses needs the outer ones
to be larger than the innner ones for readability. For example: logical
formulas with many quantifiers as on the various set theory axiom
pages, lambda expressions, higher order associative laws, lisp etc.
Also, formulas where one pair of absolute values |x| is nested inside
another pair are unreadable without the outer pair being bigger than
the inner pair. Shows up for example if you want to prove that the
absolute value function is continuous.
Why don't you just implement \big? All you have to do is check that the
next symbol is a delimiter, then pass it straight through to TeX.
