We've been using this in the Micro:bit Educational Foundation (microbit.org) to fill a gap in hardware design tooling, and get visual diffs of our schematics and gerbers during PCB design iterations. It's kinda wild that's what we ended up doing, but if you want to be sure your radio layout didn't change at all when you're making a minor revision to a different part of the board, visual diffs are perfect.

That said, next project we want to try something more integrated with EDA tools. If anyone else has followed this path, we'd love to know.
