I'd recommend putting this in the tracking bug "things to remove from prefs" after confirming there is some secondary access to the information via some other logical means like an API or OAuth.

I'd recommend putting this in the tracking bug "things to remove from prefs"
after confirming there is some secondary access to the information via some
other logical means like an API or OAuth.

It is exposed via the API: https://www.mediawiki.org/w/api.php?action=query&meta=userinfo&format=jsonfm or https://www.mediawiki.org/w/api.php?action=query&list=users&ususers=Legoktm&format=jsonfm

This could probably be removed. I can't think of a reason a user would need to know this. OTOH I also don't really see it hurting anyone either

After several applications of git blame, it appears that showing the user id on Special:Preferences goes all the way back to the beginning of phase3, as it is present in d82c14fb4fbac

I think you may be mis-reading? As far as I can tell, the user ID _appearing_ at [[Special:Preferences]] dates back to r11284 (October 2005).

This is too technical to be understandable to most users, and I don't understand why we expose it. Technically your user_id is public information just like your username, but it seems odd to put it in your preferences.

Before that it appears to have been output by the prefslogintext, which had the content:

"You are logged in as \"$1\".
Your internal ID number is $2.

See [[Project:User preferences help]] for help deciphering the options.",

You're too smart. :-( Thanks for the great catch.

I dug a bit further. It looks like this pre-dates phase3, dating back to r403 (May 2002), later modified in r766 (September 2002).

Continuing to dig, this dates back to at least r15 (September 2001) in trunk/phpwiki/fpw/specialPages.php:

$ret .= "Your internal ID is $user->id.</b><br>\n";

So now that we dug it up and found that it was probably some kind of a debug printout, can we finally decide to remove it? :)
