Who, us ?
Wow, that's looking cool.
Some minor suggestions -
Can generate_netlist have the NET format name included ?
I can see this being used across many NET formats, including of course, kiCad.
I find this harder to scan visually
ERC WARNING: Unconnected pin: POWER-IN pin 2/VSS of PIC10F220-I/OT/IC1.
so maybe put the pin NumName first ?

Other comments -
Somewhat related to this, I have a small Python script that can export NET info from PCB-New.
Currently in test format, it exports in Mentor PADS Net format, in order to give an integrity pathway check for PADS -> KiCad translator
