My spidey sense tells me that this is just a BS cover story for always-online. I cannot see a single benefit when you take in to account that game developers have to deal with the lowest common denominator.
When they shut down the servers after 5 years because "the market is too low", what then? If they are saying that these are generic compute resouces (backed by a cloud API) that any game dev can use, so that they don't have to have their own servers, this concern goes away. But point 1 still stands. But, then you will have a problem of incompatibilities with newer version of such an API.
