For people wondering what this is useful for: I've been using this as a protocol for a project connecting a Raspberry Pi to a microcontroller project. Currently I'm prototyping using the serial transport, but at some point I will likely switch to using I2C to accommodate a more minimal interface between the two and allow for more devices to be connected to the RPi. This makes it so that I can swap out out with minimal changes to the code on both sides and keep a standard protocol in place. Also the libraries are pretty easily to use, so it's a little nicer to work with than rolling my own serial framing protocol.
