A new list was advertisted as LIST-1 rather than LIST-L. If I make the LIST-ID header be LIST-1, will subscriptions work as desired? Seems that it will. After a month or two, I can put the LIST-ID tag back to its proper value. As you can tell, I'm not totally clear about what LIST-ID is used for. I see, in reading 1.8a release notes, that LIST-ID is used to establish a "long" list name. Also just looked in the draft "A description of list header keywords Listserv for VM" which makes me think it will work.
