He said that while he is focusing on the procedural steps, I or anyone else could publicly express their concerns about NIST Suite B during the open-mike portion of the session.

We ought to address secure private key generation by CAs, secure delivery to subscribers, and secure deletion of subscriber private keys from CA systems.  We ought to look what we already have written and then to policies that others have written as guidance for improvements to CABF policy.
