It wasn't mentioned because we only launched Docker for AWS and Docker for Azure. We only had the bandwidth to ship 2 versions at the level of quality we wanted, so we picked the most frequently requested providers. I think GCE is a great candidate for the next batch of releases. It all depends on demand. Would you use it?
