In the states with mandatory promotion/relegation, they deal with many more divisions -- probably a necessary evil to keep divisions from ballooning or dwindling in size, among other reasons. With more divisions the difference between the top and bottom gets smaller, and on a given day a decent division 3 team can give a decent-to-lower level division 2 team all they want.
With just two divisions, it seems to me that the SC clubs do a decent enough job of figuring out where they belong competitive wise. There are exceptions in SC just as there was in the GA teams I examined at the top of this thread. So if SC stays at two divisions, then there probably isn't an urgency to deal with mandatory promotion/relegation.
I believe there might be value into adding a 3rd division at the U13/U14 level with the idea that teams might need to go to a "home and away" games or have some 'cross over' games with each team to get enough games to keep bamr happy, but the games will tend to be more closely contested and that should help both teams regardless of the result.
