If only 4% of all enterprise spend is on any cloud provider and AWS has I believe 36% of the market, and on top of that AWS has 260 services (at least that’s the number of distinct IAM resource types), I would think there was a larger third party market for Office extensions and dark matter developers doing Office/Sharepoint automation than who cared about a new AWS feature.

There are a lot more people working at AWS dependent on MS office than MS people depending on an Amazon service…..
