Interesting! Likely, CentralAuth should fire a new hook whenever a new account is 'a local account record for the given wiki to the central database' is added. We'll also want to add a new JSONSchema for a mediawiki/centralauth/account-add (or whatever) event. Then the EventBus extension can then produce the event.

This seems quite an odd fit for an event stream given the nature of the data published, is this stream used significantly, are there connected clients?
I think we should be open to consider to turning it off.

If so, we probably need to clean code here: https://github.com/wikimedia/mediawiki-extensions-CentralAuth/blob/master/includes/CentralAuthUser.php#L1921-L1934

Ya, before we create this steam (and expose it publicly), we should know why we need it and if we should keep it. Maybe we should, but if we don't need it...let's not keep it?

Users in #central are:

10:56 :: Users #central
10:56 [@rc-pmtpa] [ natuur12] [ Steinsplitter]
10:56 [ BanBot  ] [ GVMBot] [ RxyBotLT] [ SULW         ]

Few users for sure, we could track them down and see if this is needed or not?

@Legoktm @Krinkle hi :) do you have any context about the above bots? And if we need to keep #central feed long term?

From https://www.wikizero.com/de/Benutzer:GiftBot GVMBot seems to be a vadalism fighting bot, this data stream is probbably not of much use for that

With this low usage I think we can plan on turning the stream off, data seems quite an odd fit for a public stream in any case, now we will need to remove the code from central notice that is publishing those logins.

Also used by SULWatcher to power the #cvn-unifications channel on Freenode, which in turn has other workflows and bots operating on it.

https://wikitech.wikimedia.org/wiki/Tool:Stewardbots is a great respource, nice, @elukey we can file a phab ticket to stewardbots projects letting them know we are thinking of turning this stream off.

Just to note, @Natuur12 and @Steinsplitter are Commons admins, they likely use this channel to track vandals, LTAs etc. RxyBotLT is a bot operated by @Rxy, a Wikimedia steward. I assume he uses this channel to track and lock a LTA called ISECHIKA. No idea who is the operator of BanBot but it apparently posts (non)abusive and (non)trollish usernames to #wikimedia-stewards channel.

The channel is indeed useful, keeping it would be helpful :-)
