A few inline replies.

> These seem to be on your list below. I think we should stay away from
anything that is about specifying best current practices because as
far as I can tell all but the most trivial ones (here is how to safely
run a TLS server or something) are contested. For instance, even
retention period has very strong views on both sides.

[JL] Fair point that there may be some issues agreeing on BCPs. On the other hand, as an operator, some convergence on and recommended best practices may be quite helpful. So I would prefer to keep this in, and not shy away from debate on this because I suspect we may eventually find rough consensus in some areas and those could be put in a BCP (while the others where agreement is lacking would not).

> This list of practices would be much more accurate if it included the
resolver-level DNS practices that we are trying to mitigate using DoH,
including NXDOMAIN synthesis and collection of user browsing history
data.

[JL] No reason why NXDOMAIN and other stuff should not be in scope, whether as part of expression of resolver policy or otherwise.  A lot of this is opaque today. As well, practices are more in flux now that perhaps in the last 10 years, so I think work here would be interesting.
