So far so good. > A very simple approach would be <List-Id magic here>; Not so good, since there are lists that do't have list-id and spam that does. There's a large class of approaches that either require registration, the various third party signers, or would likely work better with it like my double signing thing. But it's clear to me that if there were an easy way to register lists globally, we would already have done it. Large providers have a pretty good idea of who's sending them list mail, e.g. Google notes in in their DMARC reports, so they can use their own list if they want. Small providers will have to do other stuff, but ad hoc approaches like adding lists when users compiain is probably OK. So I'd just note when something needs or would be aided by registration but not waste time trying to invent a way to do it.
