Feature Name

Support client hydration for in-memory API

The Desired Behavior

I want the client to be hydrated with the same in-memory API data that the server has.

Your Use Case

As an app dev, I want to use client hydration with the in-memory API.

Will likely have to be implemented with a full in-mem rewrite
