That last sentence is basically what I said about both of my drafts, and that logic was shot down. Once you've decided you don't like the arbitrary changes, you know who to blame, but you still have to decide what you like and what you don't. Yeah, now that I look at your drafts again, I see

A database is still needed of which domains will have an outbound mail stream with two signatures. Sorry, no, that's completely wrong. Please reread the draft. I have not yet taken the time to fully understand the weak and strong signatures idea, but if I may be forgiven for commenting

This can be solved by having the owners of mailing lists publish a yet-to-be-defined DNS record in which they proclaim the presence of a mailing list within that domain. That's unlikely to work, because malicious people can publish anything that legitimate lists can. There's a fundamental rule
