require it.
I don't see any practical difference between a stack that increments with a
push and one that decrements with one; mostly it seems like a detail.
It's pretty much a given that any situation involving a subroutine that can
call itself demands a LIFO stack structure of some sort, though. How
else might one implement recursive calls otherwise?
