Google App Engine Management and Monitoring API

Google App Engine provides a very basic high-level system status page. It gives a quick on-off view of which of the GAE services are running and which are not. I am wondering if Google has any plans to provide a more API based and fine grained access to some of the monitoring and management data or have they purposefully left that gap for third party developers to build something against it. Of course it is fairly straightforward to write a quick-and-dirty monitoring system by running things inside GAE and doing real-time reporting (such as running monitoring GAE cron jobs with a API/UI interface). Google can do a much better job at it of course, given the fact that they have a lot more real & physical (vs. interpreted/derived) monitoring data that they already must be capturing. Maybe they just didn't get to publishing it yet.
