Protocolbuffer Binary Format (PBF) Documentation or Examples?

[TomNeer]

ArcGIS Enterprise added support for the PBF output format in 10.7.1. We are having difficulty finding any documentation or examples on Esri's implementation of PBF in either the Developer's documentation or Esri's Github outside of Vector Tiles. We would like to look at using this format with some larger datasets. Any pointers would be appreciated?

I've added some info on how to parse the geometry bits over here. I've just reversed engineered things as best I could but it seems to be working, and hopefully in due course I'll publish a little npm module for doing it.
