First of all end-users would not care much what protocol it is when
"you've got mail" pops up.

And for designers, programmers, and quicker implementation its quite a bit 
better if new protocol and old one share certain components. For example 
MIME encoding/decoding, etc. It would faciliate process  if protocol can 
be implemented on same mail server software that would be able to decide 
based on certain dns or other parameters what protocol to use when sending 
email to the other end.

And look at the example of IPv4 vs IPv6 - IPv6. While there are substantial 
improvements in features available with IPv6, as far as implementation and 
design and application programmings, its not that different.

state machine very early.  Or in other words, I could see making the 
new protocol similar enough to SMTP that a single server could 
implement both, but that might just invite confusion.
