Hey,
It happens quite often that people add a temporary config variable to the
code and then mediawiki-config repo, they remove it from code and forget to
remove the config in mediawiki-config. My quick check found these config
variables to be unused:
$wgSpamBlacklistEventLogging
$wgUseContributionTracking
$wgMFLazyLoadReferences
$wgMFExperiments
$wgDepictsQualifierProperties
$wgMediaInfoEnableOtherStatements
$wgGEHelpPanelSearchEnabled
$wgDisableRollbackConfirmationFeature
$wgCirrusSearchEnableSearchLogging
Unused config variables are bad because they make our overly large config
file even bigger (IS.php is already over 20k lines) and it can be confusing
(like
https://phabricator.wikimedia.org/T225183). I will add more unused
config variables to the list by improving the search but please check and
remove them if you introduced any of the aforementioned variables.
Thanks
Best
