Might as well ask an even more basic question:
I had the impression that multi-recipient RCPT-TO usage had essentially
disappeared. The growth of sending per-recipient tailored messages seemed to be
the cause.
If my impression is wrong, is there any useful (and accurate) characterization
we can make of different types of SMTP (relaying) usage patterns and their
popularity?
