irc1002.wikimedia.org provided —and still does— a default cloak for all users (`@anonymous.user`). Since T376014, irc.wikimedia.org points to irc1003.wikimedia.org, which no longer provides a cloak.
As I understand, IRC users are [[https://github.com/paravoid/ircstream|no longer visible to each other]] on the new ircstream service, so I suppose a cloak may not be necessary. Still, a user joining irc.wikimedia.org may think their IP is exposed. Is this intended, or should a cloak be enabled on irc1003.wikimedia.org as well?
It may be useful to mention this new behavior in the MOTD shown when joining the server. I was initially confused when I noticed my IP was visibile and the IRC channels suddenly had no users (while bots using IRC streams were clearly still working). To find out about these changes I had to first find T376014, then [[https://wikitech.wikimedia.org/wiki/Ircstream|ircstream on wikitech]], and finally the [[https://github.com/paravoid/ircstream?tab=readme-ov-file#ircstream|ircstream's readme on GitHub]].
