With regard to the first two of these points, Databases / Persistence and automated REST APIs I fully agree with the problem and I'm working on it pretty hard. My e-mail's in my profile if you want to chat.

However, the nature of writing a good, broad, solution as a third party is you have to capture some senior engineers for long hours, which costs money. And it's not clear to me if there's enough money available, for a third party to build the kind of broad-reaching solution that would be nice to have.
