I think there is a definitive rule on stopover allowances, but the problem -- as you note -- is that finding out the "valid routing" is a bit of a challenge, and if you don't know the valid routing then you don't know if you can stopover there or not.
It seems like there should be an easily-accessible resource for this on Delta.com whereby for any given city pair, one can see the valid routing/connection cities for travel between those two airports.
But that would make it way too simple.
Just like clearly stating in the fare rules whether a fare is refundable or not, which is also quite obscure.
