How to override Connector API to implement custom logic?

I know that the Connector API is still in beta, but I was wondering what the suggested approach is for augmenting, extending, overriding, etc. connectors? Currently, one can set the enable_connectors flag to use connectors, but there doesn’t seem to be any “handy” way to configure said connectors.

This isn’t something I need to implement or use immediately, but rather a curious question about the plans for the API. I think the concept is very neat and introduces great modularity for handling transformations on inputs and outputs of a given RL policy.
