You should read more carefully.A lot of hindsight bias going on in this thread.
I did not see a single instance of anyone mentioning that this was anything but an Xbox One exclusive feature in threads previously discussing Azure/cloud processing for console gaming.
I mean, it makes a lot of sense in hindsight... but you're been dishonest with yourself if you didn't think about this until now and are concluding that this is obvious.
What was always an "Xbox one exclusive feature" is the marketing idea that game developers will actually widely use cloud computing to offload rendering tasks in a console game. Simply because no one else was in dire straits and needed to make up something which makes no sense on a great many levels. And even then, as we can see some people pointed out the folly of that.
