The issue is insane. Note that prior to Snow Leopard, Mail.app generated
The "problem" is that format=flowed was not recognized as meaning
anything by Outlook. As a result, Outlook at best exhibited the expected
behavior of a format-ignorant MUA and presented a message with fixed
linebreaks. At worst (depending on version and config) it would re-wrap
the message and put a notice to the user that it had removed "extra"
linebreaks across the top of the message window. The only advantage to
QP is that for years after the widespread adoption of RFC2646 and even
after the "DelSp" tweak was added in RFC3676 the latest versions of
Outlook used and only understood line-per-paragraph text encoded with QP
as *the* way to do reflowable plain text. I don't have a definitive
direct statement from the Mail.app people at Apple or from anyone who
speaks for Apple, but Outlook-friendliness is the only rational reason
to mimic its misbehavior. I have been told informally by someone at
Apple who does not work on Mail.app that this was the reason for the
downgrade in what it generates and that there was some stubbornness
towards considering counter-arguments.
I have heard conflicting reports about Outlook 2010 (which I can't
readily test myself) supporting RFC3676. This is mildly amusing, but I
have a sick sense of humor...

That would be better than the Exchange/Outlook misfeature. If this ever
becomes something you have an urge to implement, please also keep in
mind that an imprecise or incorrect translation of the standard codes
into plain language is worse than none. Also, some uses of the standard
codes are technically inaccurate for strategic purposes with the text
part of the reply describing the real reason for failure in a manner
that only a human can come close to interpreting.
(FWIW, it is possible to make my Postfix machine say "554 5.1.1 Message
Delivered Successfully" but I am known to be a jerk.)
