Slava @ RethinkDB here. The main goal behind Fusion is to let people get started quickly, but eventually any meaningful app will outgrow the Fusion API. When that happens, instead of starting Fusion as a stand-alone server on top of RethinkDB, you'll be able to load it into Node as a library and integrate it with koa/hapi/etc. That will provide the Fusion API to your node app, and an upgrade path for modern complex applications. That's an essential part of Fusion and will ship along with v1.
