Sender-ID could've been useful too, but it turns out it wasn't. In hindsight, I don't think any amount of guidance would've changed that. Rather, it seems to me the community understood the implications and made its choice with its proverbial feet. This proposed rechartering is meant to acknowledge this reality, much like RFC 6686 did. I see this the same way.

Simply, no one has said how to do it. > It seems to me that any system that seeks to identify a list subscription or forwarder with high accuracy relies on either (a) humans to be error free and never lazy, and/or (b) lists to all behave according to some standard that doesn't exist.

I don't think I've seen any, but maybe you're privy to other conversations. -MSK
