 * The RFC authors may solicit early feedback while preparing an RFC, possibly before sharing publicly.
    * If requested, the TC could help to nominate a small group to shepherd the RFC.
 * If the RFC potentially contains information that could be certification-sensitive (guidance to be shared), send a note to security@opentitan.org first for feedback.
