I think, honestly, that Microsoft is feeling pretty happy with how things are working with steam right now - they've probably only got to do a very minimal amount of work to integrate with the platform while internally they have MS Game accounts that tie everything together for any of the tracking needs they have. I'm sure they'd love to convert all of the MS Games users to their own store but they've managed to extract a whole bunch of unexpected business from AoE2 and other titles and they're probably hoping to minimize any damage to the ecosystem.
