So, clearly, under some circumstances the network operator wants to
expose this information, because there was the request for that feature.
The question in my mind is what circumstances are those, and what
additional information needs to be provided here.
There is always a balance between the private cloud case which wants to
enable more self service from users (and where the users are often also
the operators), and the public cloud case where the users are outsiders
and we want to hide as much as possible from them.
For instance, would an additional attribute on a provider network that
says "this is cool to tell people about" be an acceptable approach? Is
there some other creative way to tell our infrastructure that these
artifacts are meant to be exposed in this installation?
Just kicking around ideas, because I know a pile of gate hardware for
everyone to use is at the other side of answers to these questions. And
given that we've been running full capacity for days now, keeping this
ball moving forward would be great.
