Not in the real world.

Sendmail is the expected norm. Its like buying a car and finding it comes
with wheels. Tracks may offer more functionality, hovercraft may offer more
excitement, but the default expectation is wheels.

Ditto sendmail as mail server.

We have a lot of "best of breed" stuff in Extras precisely because its not
the expected norm. Thus joe is in extras and vi is in core.
