I'd be curious as to what the specific end applications are, are there any you can share? I'm familiar with the tooling and played with it quite a bit... But n

  Sure. It's hard to make this justice on a single comment, as there are lots of applications. Basically, any scenario with small or medium size datasets where you would use generative models. PPLs are just a way to encode generative models and get an inference engine compiled for you, instead of needing to write one. For example: * Landing the Apollo on the Moon or tracking systems used by e.g. Sidewinder employ Kalman filters. See Example 24.4 (p. 510) [1]. * Predicting ride demand on heavy-tailed time series. Uber does this all the time [2]. * Estimating the effect of some policy on data with hierarchical structures (State > County > Individual observations) [3].
