As evident from the redlinks in URL. This was set to true per explicit community request because most of legitimate Meta-Wiki users come from other Wikimedia projects, of course. It was disabled with chance-id ab6dbfa0 only as a workaround for bug 44754, from what I can see, so it should be restored now that the bug is fixed. (This would have required less that 7 months to notice if someone had warned the community...)
Change 83355 had a related patch set uploaded by Nemo bis: Revert temp workaround: $wgNewUserMessageOnAutoCreate true on Meta-Wiki https://gerrit.wikimedia.org/r/83355
