Good to know.
OP, if you use a laptop to install GOS, your laptop could save that you connected a phone to your computer. If your computer gets compromised. The other phone won't save anything.
If youre concerned: boot off of a USB into Linux to avoid this or install gos on other phones using your gos phone (have 32GB of free space I think)
This doesnt seem like an issue at all honestly. Because the computer might remember either: "a pixel 9 is connected. And another one. Another one" or "device 48583838 connected." Which could be a gibberish serial number that means nothing to people.
