There's been some worry in some circles because Bluetooth low energy profile specifications have lagged the release of the Bluetooth 4.0 core spec (released in June 2010). Therefore, the adoption of the first Bluetooth low energy profile specification, Health Thermometer, is cause for celebration. Besides enabling health-related use-cases based on temperature measurements, this profile has been used as a pipe-cleaner to pave the way for future Bluetooth low energy profile specifications to come. You can therefore expect many more BLE specs to be adopted in the near future. Stay tuned!
You can find more information about the profile on Mike Foley's blog: http://www.bluetooth.com/MikesBlog/Lists/Posts/Post.aspx?ID=16. The specification itself (for both the profile and the associated services) can be found here: https://www.bluetooth.org/Technical/Specifications/adopted.htm
