Some abuse of Delivered-To to trigger bounces has been reported now and

The thread you cited only describes the abuse as:
If mail arrives for a recipient

Viktor,
I'm not understanding.
Since Delivered-To is meant as an indication about the message
containing the Delivered-To, I'm not understanding what the 'already
listed' reference means.
It seems odd that a spammer would send a message designed to be
rejected, other perhaps for generating problematic bounces.
To the extent the description is meant to refer to a broader set of
mechanisms and activities, can you elaborate?
