Using Phrases

I believe that hello home phrases are the most powerful things in SmartThings. It seemed that maybe they were not exposed in the API, because I didn’t see it in the documentation, no smartapps seem to call them and IFTTT doesn’t call them. But I noticed in the video for UBI on the blog, they say they are using phrases… So can someone confirm this? Perhaps it is a recent addition to the API? If so, it would rock if someone could update some of the more popular Smartapps and the IFTTT chanel? I think that would boost the value of ST significantly!
