This problem with this document is that it does not, in fact, describe Best Current Practices. The description of the interaction between DKIM and mailing lists is pretty good. But of the advice it offers, only one item is in fact done in production, signing outgoing mail, and everything else is hypothetical. We can have (and have had) arguments about whether it would be a good idea to do what the rest of the advice says, but the reality is that nobody knows, since we haven't tried it other than perhaps in tiny experiments. I'd suggest changing the category to Informational or perhaps Experimental, after sending it back to the group and telling us to distinguish between what's current practice and what isn't. On the other hand, if it's OK for BCPs to consist of Our Unimplemented Speculation, I have a variety of BCPs I'd like to send along.
