Why do we need another metadata service when the registry is there? That
has an HTTP API so that's the service. What am I missing??

The point about a local API was different: we can have the agent in the
cartridge talk to the above HTTP API and expose a simple local API, with or
without protection. That could even push environment variables out so that
code can pull the values out directly. That's what Paul wanted to do a long
time ago.

Sanjiva.
