Charlie's difficulty may stem from the fact that I haven't offered such a 
conclusion in the three short posts I've submitted on this topic.

There is no big problem, that's for sure.  I merely note parenthetically, 
in passing so to speak, that List-ID prevents nothing, solves nothing, 
assures nothing, and simplifies nothing, and that it will be hard to parse 
meaningfully, difficult to enforce correctness syntactically, widely 
subject to abuse by spammers, and confusing to most of the community it's 
foisted on.  However, it has a very pretty RFC, and it gives software 
authors something new to implement and fight about, and the listerati a new 
stick to beat mere users and working admins with, so I am 100% on board and 
in favor of it.
