If you don't like bogus bounces, implement SRS or SES for all your

(Mark [the asarian-host Mark] has a web page on how to do this with
sendmail.  His scheme needs some tweaks for multiple-MTA sites, but
any decent sendmail admin should be able to adapt his scheme to local
needs.)

ACK.  And I also have an RPM that does this with python for sendmail.

Batch processing is so much easier and cheaper that I think large mail
services are going to do it, no matter how much people wail about it.

Yep, and if they check SPF, we won't even wail about it.
