Yes, you are right it is a minor detail, some might want different ways of displaying the links, ie category names instead of numbers, or just a completely different way of doing the links:

instead of:
listings/new.html

they might wish to make it:
newlistings.html

instead of:
categories/9.html

maybe:
categories/9/categoryname.html

I haven't ever used SMF, but it does look better than a few others I have tried. Is it easy to skin?
