I've got something similar in my setup, only with a lookup so that I can
specify the folder names. This is important because one batch of
mailing lists I'm on (Slim Devices) doesn't follow the usual "app-forum"
naming pattern, and simply names their lists "discuss", "development",
and "unix". So I'm using:

if ${lookup{${address:$h_List-Id:}}lsearch{$home/.forward.lists}{$value}}
         matches "(.+)" then
    save "$home/Maildir/.Lists.$1/"
endif


I used to do the automatic folder creation you were doing, but turned it
off (by adding the if and the matches) and limited it to only create
folders it found in the .forward.lists lookup, because I found it
annoying to have new folders created for very sparse announce-type lists
like Cryptogram or putty-announce.
