LGTM! I think it was @Jimbo4350's idea with reexposing stuff. I'm leaving approval to him if this is the direction we want to follow.

We need to discuss how we want to expose things on a module basis. Can you create an issue for this? We have strayed far from what was originally envisioned with the Cardano.Api and Cardano.Api.Shelley but I am partly to blame :).

I think this is fine. The alternative to this would be users traversing the ouroboros-network. Exposing this here would likely help inform how the ouroboros-network can be consumed.
