The way I expect it to work will be pretty much how Reika explained. However, this would not only streamline the UI for initiating crafts, but also open the door to including some high level recipes that you need to learn via quests or some-such content. Sort of like an endgame for DoH.

Essentially, the vast majority of things you can craft will be learned automatically by leveling, while some high skill recipes can be made so one has to learn them via content.
