Flam^H^H^H^H value judgments aside, does DMARC also change the long

No, DMARC should not change the principle operation of SMTP, save for
additional checks that messages must pass. All other aspects of sending
email should be the same.
MTAs should continue to send bounces back to the SMTP envelope address.
Though, ideally the MTA would reject the message during SMTP time
instead of accepting and bouncing the message.
DMARC does offer the ability to have reports about DMARC failures sent
to the domain publishing the DMARC record.
