    Does this updated Abstract resolve your non-blocking concern?

       RFC 8226 specifies the use of certificates for Secure Telephone
       Identity Credentials, and these certificates are often called "STIR
       Certificates".  RFC 8226 provides a certificate extension to
       constrain the JSON Web Token (JWT) claims that can be included in the
       Personal Assertion Token (PASSporT) as defined in RFC 8225.  If the
       PASSporT signer includes a JWT claim outside the constraint
       boundaries, then the PASSporT recipient will reject the entire
       PASSporT.  This document updates RFC 8226; it provides all of the
       capabilities available in the original certificate extension as well
       as an additional way to constrain the allowable JWT claims.  The
       enhanced extension can also provide a list of claims that are not
       allowed to be included in the PASSporT.

    This was raised during Last Call, and the current quotes are consistent with RFC 8225 and RFC 8226.

    Someone asked to a reference at some point along the way.  There are other early documents from the PKIX WG that also define the term, but RFC 4949 seemed to have the least baggage.
