I think a compromise will be somewhere in the middle.  I think most people would be OK with TXs that don't have enough fees for P2P transfer to stay in deadmans land.  Most people are stuck in a situation where they payed enough to get it into (and keep it in) the pool, but not enough to get it out.

If we could get CPFP that only worked on TXs that met the minimum threshold for peer propagation, then I think we would be in much better position to battle this spam flood.

Right. The issue (AIUI) is that, right now, even though transactions are evaluated for inclusion as a group with CPFP, they're not yet evaluated for relaying as a unit, nor can they be, because the current p2p protocol doesn't have a way to send multiple transactions in a single protocol message to signify that they should be evaluated together.
