…or it could be caused by the hook defined directly in configuration here: https://gerrit.wikimedia.org/g/operations/mediawiki-config/+/c901262a58781743f53ea8792c9de2c5467a4d9e/wmf-config/CommonSettings.php#2669

Checking $user->isAnon() is suspicious.

Yes, that looks like it to me also. Probably should check isTemp() also.

Might need unbreak now for this one.

If I'm reading this right, this means that before the bug, IPs and non-autoconfirmed users (<10 edits & <4 days) on enwiki could create articles (in draftspace). After this bug, they cannot. We're probably missing out on a lot of page creations a day, giving a bad experience to these newbies, and not following our local policy on this.

Looks like a check on fawiki is prudent to see if they are affected as well.

Oh, I didn't even see Matmarex's comment. Wish I had seen it. Would have saved me some code searching.

I'll backport the above patch in 12 hours if I'm awake during that backport window. Anyone else should feel free to backport it for me.

I have landed on the same solution. Will be happy to queue it for the UTC morning window in 6 hours and follow up from there.

Based on this data, the impact of this on enwiki is about 76 less pages created per day.

Only about 43 per day - we're losing the pages that would have been created by ips, but registered non-autoconfirmed users were still creating drafts on 11/5 after the temp-account rollout.
