This document contains many useful improvements.

On the subject of blocked queries and responses, the proposed text is
excellent.  It doesn't actually fix anything (just adds a SHOULD and some
informative text and guidance), but it does point out some of the challenges
in this area, and will be helpful in convincing the CA/B Forum that the
current BR CAA error handling requirements are impractical in the world as
it exists today, and need to be revised.  The policy discussion will be much
easier with the documented, specific examples of why the current failure
handling rules cause a lot of pain for people trying to get certificates.
Perhaps it would be worthwhile adding text to clarify that these sorts of
failure can prevent issuance of certificates, even for domains that don't
use and don't want to use CAA.  When CAA was originally being sold, it was
claimed that if people didn't want to use it, they wouldn't be affected, and
that has turned out to be very, very far from the truth.

The draft unfortunately prioritizes a few issues (the CNAME issues and
blocked queries), while ignoring some more critical issues, like the fact
that the RFC 6844 grammar contradicts the examples.  Corey had an excellent
proposed fix for this issue.  It should probably be incorporated.
