Eh. I agree, Khaled, on the "clutter" point you made. The specific event that I raised... the Nick event... is just in such high proximity to Join/Part/Quit that I feel it alone should be blessed with the address displayed. It's a CHANNEL IDENTITY event.
All the other events you've mentioned: Topic, Mode, Kick, don't necessarily warrant an address appended to them, because they are not in the realm of identifying someone's presence in the channel as Join, Part, Quit, and Nick are.
To phrase it in another way: The Nick event is a nearest equivalent to someone Quitting and Joining the channel again with a new nickname.
In practice, someone changing their nickname several times, before changing their nickname to that of a known channel op, can help obscure someone's identity enough that people become confused if they're the real deal. It's very difficult to scroll back through all the nickname changes (tracking each one) in the log to find their original Join event.
