Not really. Mojang could and should do a lot more to leverage Minecraft. I get the impression that Notch unexpectedly wound up with a huge infusion of cash and didn't know what to do with it besides hire a few friends and make an MMO based on programming microchips, complete with its own assembly language.
The amount of torture they put the Minecraft Coder Pack guys through is atrocious. There is no reason why MC should not be "source available" with some creative licensing and host a Steam Workshop-esque mod management center, play Valve and take a cut of each purchase.
All the community has to go on is the Twitter accounts of Mojang's employees and /r/minecraft. Minecraft is awesome, but it's painful to think of the potential that's wasted there.
As a involved member of the Minecraft community. I can tell you that there is work being done on a Minecraft API, but I have no clue on a ETA. Also, I don't think they really have any plans on how to monetize things.
