Enable_coprocess config change?

Previous I used to have this in tyk.conf

"coprocess_options": {
   "enable_coprocess": true,
   "coprocess_grpc_server": ""
},

Pulling down the latest quick start as of 2.5.2, noticing that block is gone and now just

"enable_coprocess": true

exists, is this the new correct config syntax to be using?

How did you get that tyk.conf? The config has not changed, would be good to know how that slipped in…

From the pro demo due to this: Docker quickstart 404
