which implies, that the mail was accepted by all but mailing-list(_at_)example(_dot_)org?

The problem I see is that 550 does not imply "accepted" at all. 550 is not a partial success code.

If its not already clearly stated in 2821 and in 2821bis, then maybe there should be a statement added to 2821bis stating to the effect that a 550 not only means a permanent rejection for the transaction, but it also *implies* to the SENDER that the recipients ARE NOT going to receive the mail - atleast not "officially."

I really hope we don't open the DOOR to the idea that a SMTP server can begin to tell the SENDER mail was rejected but actually LIE about this delivery status and delivered the mail anyway.

I can understand and see how GREYLISTING implementations can help "mold" the thinking in this directon.
