Yea, They could also meet them in Salisbury, Falls Village, Cornwall, Cornwall Bridge, or Kent and have pizza. Bringing it up to a summit makes it seem more cool for the people doing it.. not the hikers. they will go around telling everyone that they were "trail angels" and saying how cool they were.
Also, what if something slows them down or the people can't meet them with pizza... they just left their resupply PLANNING to have outside food brought to them. so they are either unprepared or carrying an extra day of food for no reason.
