"OK we want our website to know which software you have installed"
"You can't do that"
"Sure, but we want to do it anyway. Maybe we have the software listen on a port and then we can try loading stuff from that port?"
"No. Zoom did that so it got banned"
"OK what about we edit their computer's local config?"

@sil I remember back when any website could enumerate all the Philips Hue bridges on your local network.

The bridges would ping their cloud servers, and then they offered a REST API that would provide the self-reported local IP address of every bridge that appeared to share your public IP address. That API used CORS headers to make it usable from any website.
