Wondering if collection of article review statistics is running.
Have users been granted review rights via https://hi.wikipedia.org/wiki/विशेष:सदस्य_अधिकार ?

A list of users currently granted reviewer status can be seen at https://hi.wikipedia.org/w/index.php?title=विशेष:सदस्य_सूची&group=reviewer

In addition, admins have reviewing rights as can be seen from https://hi.wikipedia.org/wiki/विशेष:सदस्य_समूह_अधिकार

Wierdly enough, it appears that https://hi.wikipedia.org/w/index.php?title=%E0%A4%B5%E0%A4%BF%E0%A4%B6%E0%A5%87%E0%A4%B7:%E0%A4%85%E0%A4%A8%E0%A4%BF%E0%A4%B0%E0%A5%80%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%BF%E0%A4%A4_%E0%A4%AA%E0%A5%83%E0%A4%B7%E0%A5%8D%E0%A4%A0 works while https://hi.wikipedia.org/wiki/%E0%A4%B5%E0%A4%BF%E0%A4%B6%E0%A5%87%E0%A4%B7:%E0%A4%85%E0%A4%A8%E0%A4%BF%E0%A4%B0%E0%A5%80%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%BF%E0%A4%A4_%E0%A4%AA%E0%A5%83%E0%A4%B7%E0%A5%8D%E0%A4%A0 doesn't.

Although the percent encoded form of both urls is the same, for some reason accessing the page with index.php works while the regular wiki url doesn't work.

If I understood the flaggedrevs config correctly, it seems that its no longer enabled for the mainspace.

That is not the case:

demon@tin ~$ mwscript eval.php --wiki=hiwiki
> var_dump( $wgFlaggedRevsNamespaces );
array(7) {
  [0]=>
  int(0)
  [1]=>
  int(6)
  [2]=>
  int(10)
  [3]=>
  int(828)
  [4]=>
  int(4)
  [5]=>
  int(14)
  [6]=>
  int(100)
}

I'm not entirely sure why the special pages aren't showing up for hiwiki.

Sometimes it's set in wgSpecialPages, sometimes it isn't...

This is triaged as "high" - is there anyone currently working on this?

This is being caused by the same thing as T132454: Some OAuth special pages are not recognized ('no such special page') - FlaggedRevs is registering special pages using $wgExtensionFunctions which is too late. See T132454#2213091
