Really? In the podcast they say it's similar to what they used for over a year in production, made available to get feedback from others and that's why it's released as alpha.
Pedestal is a culmination of those efforts into a new set of libraries. Some of the code from other projects inspired what there is today, but an even greater portion was created from scratch to make it more generally applicable. We haven't had the chance to use this incantation of the ideas in production yet, but we wholly intend to. We hope this experience, and that of the community, can help us bring this to beta or fully production ready.
