for myself: (C)

I started sorting my inbound email into different folders on a per-list basis 
back in 1995 or so, and that predated RFC2919 List-Id (2001). So, I sort on To: 
or cc: fields having the list's email address (which can have minor annoying 
issues from time-to-time, but aren't a big deal overall). I've been doing this 
for so long that it never occurred to me to change my practice.

Also, it seems support for RFC2919 List-Id is not universal even today -- some 
presently active lists I'm on don't employ that header field, tho a search 
across my archives reveals that such lists are in a distinct minority.

Another aspect to this depends on what MUA folks use, as Murray alludes to. 
I.e. whether using list-id is even possible.
