I can't say with certainty, because I think it touches back on the
issues previously discussed in the CA/Browser Forum and in Chromium CT
Policy list - which is that a variety of solutions exist, some
technical and some policy, and the appropriate solution will likely
sit somewhere between the both.

My goal in sending this was to check to see whether there was
consensus, say, for a client rejecting EE certs that were accompanied
by SCTs from name-redacted CAs, because in talking with various people
involved in the space, I was seeing conflicting answers about "what
the spec said".

Your interpretation is aligned with how I saw it - that client policy
dictates the acceptable form of SCTs - which, to me, also implies that
a client that only wishes to recognize EE SCTs does not even need to
parse/recognize such SCTs. That is, the spec describes the technical
means for it, but it's not mandatory for clients to accept/recognize
it as complying with policy. That's why I hoped that, if there's
consensus on that interpretation, it might be seen as a an opportunity
wording tweak that doesn't undermine consensus, rather than a more
significant action (like moving to a redaction spec)
