BATV should not trigger any bounce as this only changes the local- part of the bounce-address (a.k.a return-path). BATV allows quick rejection of the session when a spoof is detected before any message is exchanged. This should alleviate your concerns about bandwidth. It would also depreciate this tactic and further reduce related traffic. Being sensitive about spoofed DSNs, one would expect to hear accolades for BATV rather than berating.
