I’ve thought about this a lot. I think it’s the right thing to do because as the power 5 shrink to the power 2 you have to keep the Sub-Power 3 engaged. The Big 10 and SEC will continue to rule, but this keeps everybody else engaged and watching. If you disenfranchise the rest of CFB you lose viewers and ratings.
Lots of great teams in that #9-12 spot. I expect that they will rarely go far, but sometimes they will and I think you legitimately can say nobody is being left out.
