It's really important as people build apps (and business value) through composition of smaller services rather than composition of code that they become aware of these external dependencies. And not just at build time, but during the operation of these apps/business processes.
If you make apps and use any sort of {P,B,S,I,}aaS, do you yourself a favor and follow/subscribe/whatever to their news/release channels.
