achieves the same goal, does not require the standardization and
implementation of a new DNS RR in DNS server software and MTAs. It
requires only small changes in system administration conventions and
modest changes in MTAs.
It also has the advantage of not changing its behaviour significantly as
penetration thresholds grow.

forcing people to use the same going as incoming ISPs.
Agreed.
