List-ID is widely used. To uniquely identify mailing lists, reasonably enough. :) If you're naively using it to route mail to maiboxes, and automatically creating those mailboxes based on the value in it you're going to catch a fair bit of email that's not traditional discussion lists. Also some spam with random-ish values in the header. I have a sieve rule for each mailing list that identifies it based on the List-ID value and routes it to the right mailbox - you'll likely want to do the same. It's a few seconds of work each time I sign up for a mailing list, but that's not a terribly common thing.
