I agree with Michael here.

As users seem to ask for it, my proposal would be to add big warning signs that it is deprecated, i.e., TCP-AO should be used instead. On that aspect, the other authors could maybe also chime in.

The requirement to support MD5 stems from existing deployments of BGP that still use MD5 to secure the session. That is why the support for MD5 has been added to the BGP YANG model <https://tools.ietf.org/html/draft-ietf-idr-bgp-model-08>, using groupings defined by the YANG model in draft-scarf-tcpm-yang-tcp.

Cheers.
