Hi!
I wrote a script to detect unused wmf-config code. [1]
Specifically, unused
settings and conditional blocks for configuration that no longer exists in
MediaWiki.
The script cross-references any wg- identifiers in wmf-config with
Legoktm's Codesearch tool [2] and reports those that have no matches
outside wmf-config. [1]
I checked the CirrusSearch ones and most are indeed unused, except that
this one: CirrusSearchCrossProjectBlockScoreProfiles - seems to have a
mention as CirrusSearchCrossProjectBlockScorerProfiles - I wonder if
it's a typo.
Generally CirrusSearch uses some configs without 'wg' prefix, but in
this case it doesn't seem to be an issue.
This one produces 404.
