It seems to me that your proposed approach is anything but simple.  It 
would appear to me that you want to trade the direct, obvious, near-term 
benifits of a defined deterministic Sender Signing Policy (I'm not saying 
the current draft is perfect) for an uncertain, undesigned, and 
undocumented automated abuse reporting infrastructure.

You get to call this 'simple' from a DKIM perspective only by declaring all 
this complexity external to DKIM.
