Hi Benoit, Med, all, I support the bis definition of Tacacs+ TLS YANG.
The warning in the abstract of RFC9105 is a recommendation of security AD and a reminder when using this YANG standard. As Med said, RFC8907 published as information has security vulnerabilities, but all the IETF YANG models are published as standard. Therefore, related warnings are added to the both abstract and security sections of the 9105 per recommendations from security AD. I think Tacacs+ TLS has solve the security concern of 8907, so no need to keep this warning in the abstract. And the warning can be applied to "shared-secret" only.

The authors may have more context to share.
