Aside from the opinions that it's too late to have an explicit bounce
address be recognized (and catch-all systems could be told to
explicitely bounce it)... the biggest problem with the explicit bounce
is simple... I just send:

   MAIL From: Nick Levinson <nick_levinson(_at_)yahoo(_dot_)com>
   RCPT To: <sure-to-bounce(_at_)someplace(_dot_)com>
   ...

and you may get backscatter.  

Sure, we may be able to write that the SMTP transaction should fail
immediately, but then, that wouldn't help your situation, because you
wanted the bounce message from the remote mailer, not from your mailer.

Of course, many mail systems are unable to make the SMTP transaction
fail so soon, and backup-MXs can not do it at all, so we wouldn't even
be able to write such text.
