As I understand it, there is no way of saving arbitrary data. Being able to save progress is crucial for games spanning over multiple sessions. RPGs, any game you earn currencies or level up in, and so on. Having a database, even if limited, would be great. If this is not possible, allowing external calls could allow us to set up storage elsewhere.
Yes.
We currently have no save persistence between sessions at all right now unfortunately 
I would say this is the #1 biggest blocker for most studios right now.
Having persistence is like the most wanted thing from creators for release right now I feel like, hoping Epic can figure out something soon!
Agreed, persistence is a key feature
