Mediawiki appears to have started emitting a significant amount of deprecation messages to logstash, for example:
https://logstash.wikimedia.org/goto/7618b08032132948faa201d3fbe5de33 - "Use of ResourceLoaderSkinModule::getAvailableLogos with $wgLogoHD set instead of $wgLogos was deprecated in MediaWiki 1.35."
Along with this kafka-logging has begun alerting on consumer lag, indicating that logstash is unable to keep up with the volume of log messages.
Can these deprecated messages be quickly disabled?
