Looking at this and all the problems I am surprised the old ICE lasted this long. Considering how outdated it all is probably also would raise a security concern.
In regards to: "But the idea started to mutate even further. Why would you want to see only your ICE adapter debug information? Maybe you want to see where a connection issue is happening right now between other players."
I assume you are referring to this from an Admin management sort of side where you (as an admin) could see connection issues and this is not something every player could easily look at. As depending on which side either user or admin will depend on what data is viewable.
Only mentioning this in regards to GDPR legislation as having all users able to see current IP's they're connected to mid game can cause a fairly large security risk.
