Deltarune chapter and save menus -> filling a slot with something slightly important.
Deltarune credits sequence -> we can strongly guess there will be one looking at Undertale and the "Gallery" window. whether it's at all important is the question. it might not be important at all. or there might be exactly one interesting credits presentation trope that makes it not totally useless to code here.
