For me as an operator, the distinction between internal and public
endpoints is helpful, as it allows to easily set up extended filtering
or rate limiting for public services without affecting internal API
calls, which in most deployments cause the majority of requests.
I'm not sure what "intelligent routing" is meant to be, but it sounds
more complicated and unstable than the current solution.
Big +1 on dropping the admin endpoint though, now that keystone doesn't
need it anymore.
