AbuseFilter went from being per-wiki to being a global (Wikimedia-wide) MediaWiki extension. I think its configuration can be simplified and tidied up.
Low-hanging fruit might be consolidating $wgAbuseFilterNotifications and finding other ways to reduce the need for per-wiki variance in the database case switch.
It also might make sense to evaluate why this particular extension's configuration is still split out to a separate file. It may make sense to put it back with the rest of the extension configuration (i.e., CommonSettings.php or InitialiseSettings.php). That'll require some research and trade-off analysis.
