So all in all and for the purposes of this conversation, it's not that clever I don't know enough about the RFC'S you mention to completely answer your question though.
10 000 metre view:
RFC-2369 describes the List-Post, List-Unsubscribe etc headers, so that email programs can offer a reliable "list reply" facility, and optionally other list management functions if it wishes.
RFC-2919 describes the List-Id header, so that at least email programs can reliably spot mailing lists. In theory, this remains constant even if the list changes machine, but in practice that isn't often done properly.
Can someone ask KMail's developers about it? It's always better coming from someone who actually uses the software.
