  I have general concerns about the document, which I've raised before.  The 
document is extremely small, and offers little guidance around most 
implementation and operational issues related to OpenSSL.  I've made these 
comments before, and there appears to be few changes which address my concerns.

  For similar issues with there protocols, I would refer the reader to RFC 9190 
for discussions of EAP over TLS, and RFC 6614 / RFC 7360 for discussions of 
RADIUS over TLS.  Both of those documentations contain significantly more 
content which can guide the reader.

  In contrast, this document comes across as "send TACACS over TLS".  Almost 
every operational or implementation consideration is left as an exercise for 
the reader.  Experience shows that this is a way to get non-interoperable 
implementations.

  The document is also Standards Track.  Has anyone implemented it?

  Given the lack of guidance in the draft, and the lack of experience with 
implementations, I'd suggest that "Experimental" is more appropriate.
