Just noticed in DefaultSettings.php..

/**
 * Flag to enable partial blocks against performing certain actions.
 *
 * @unstable Temporary feature flag, to be removed before the release of 1.37: T280532
 * @var bool
 */
$wgEnablePartialActionBlocks = false;

Comment needs updating, or flag removing...

From a quick analysis, this does not appear to be a release blocker. It's a missed intent for something that would have been nice. Given that it has an open subtask, I'm tentatively adding it to the next release instead.

Probably shouldn't be tagged for a specific release at this point and probably not before it's widely deployed on WMF.

Needs removal of the config from operations/mediawiki-config once the train has fully deployed the first patch.

The config has been removed from MediaWiki, but I'll keep this task open until $wgEnablePartialActionBlocks is removed from mediawiki-config repo. I'll prepare a patch for it next week, after MediaWiki 1.45-wmf.16 is deployed to wikis.
