in theory, yes. but demographics change and programs change so a series isn’t always sustainable for that long. an example of a school that has grown a lot would be Jonathan Alder (out of Madison county). in the early 2002s they had games with the likes of Madison Plains, West Jefferson, Fairbanks, Bishop Ready, Grandview Heights, Columbus Academy, Marion Local, Lehman Catholic, etc. Alder has recently started to grow and playing D6-7 teams would not be sustainable, due to growth. not every school is a victim to this, but that’s just an example that comes to mind.
