I have used Blender running headless to generate automated slideshow service for a custom gifting song startup I was a part of. After some initial hiccups getting it packaged (running a 2.78 version while cycles was being rewritten). I can't not speak highly enough about the tools and ecosystem that the community has assembled. There is no other tool that was suitable for the type of dynamic video editing via script control that is also open source. Congratulations on the new release team!
