Just curious and who knows, maybe someone will adopt it or develop something new based on its ideas.

X.400 we're approaching it by stepwise refinement. It had X.500 which lives on as X.509 certificates and LDAP.

ISO/OSI had session layer. ie much of what QUIC does regarding underlying multiple transports.

Speaking of X.509 the s-expressions certificate format was more interesting in many ways.

OSI's session layer did very little more than TCP/UDP port numbers; in the OSI model you would open a connection to a machine, then use that connection to open a session to a particular application.

X.400 was a nice idea, but the ideal of having a single global directory predates security. I can understand why it never happened

On X.509, the spec spends two chapters on attribute certificates, which I've never seen used in the wild. It's a shame; identity certificates do a terrible job at authentication
