Robert, I fully understand you, but these times BGP is used not in telcos mainly. 

 It's happening in services. Even MySQL HA can be achieved with help of BGP protocol. 

Kubernetes, Openshift, containers, etc., changed a shape how processes are running these days actually. But that's not about that.

Imagine a cluster of 1000 containers each running a specific version of BGP daemon. With such setup I would need another 1000 containers running lldpd and exposing information about the versions. Even this won't work because of network namespaces.

Implementing huge rfcs take time, and this is very trivial to implement for any existing daemons. I'm not referring big vendors here, but more about software vendors.
