why is sendmail the adopted mta?

The OpenBSD people who were ultra conservative, still relying on Bind4
and other antiquities in the name of security have finally understood 
that this did not buy anything securitywise but greatly impeded 
usability and have converted to Bind9. Either them or the NetBSD people
offer sendmail and postfix in the base system, so it is not a
"lese-Berkeley" crime to ask for such a thing.
Just for the record; I would _love_ to see Postfix as default MTA.
