It's all a historical thing. The problem that sendmail was designed to solve
back in the uucp days is different from the problems that modern MTAs are
designed to solve. The hardest part of uucp mail was the address rewriting,
so sendmail went through amazing contortions in order to solve this problem.
Internet mail doesn't need to do any rewriting at all, so the bulk of the code
in sendmail is there to solve a problem most of us don't have.
I was fortunate in never having actually been stuck on the end of a uucp link,
but even in those days sendmail's rewriting rules often got in the way of just
getting the mail there.
The "S" in "SMTP" stands for "Simple". Not having to rewrite addresses is one
of the great simplifications.

I'm also not surprised that he gets a lot of sarcastic or snide replies. I
can't resist the temptation either.
