IIRC that document is not really intended to be standards track,
I think it is intended to be more of a BCP for facilitating explicit
secure-channels between domains that to manually configure mandatory
TLS security.  [I expect to be involved in further progress on that
document].

MTA-to-MTA at scale is opportunistic, and the relevant documents
for opportunistic discovery and use of TLS authentication in SMTP
are presently RFC 7435 and RFC 7672.
