I think this may be unnecessary. Instead of having a factory class that allows it to be swapable, it may be good enough to just directly modify a single backend. Tychay (talk) 17:36, 10 January 2013 (UTC)
Where to find this extension?
@Mmullie (WMF): I can neither find a code location, nor a Phab project, nor any trace in InitialiseSettings.php that this extension is or was deployed on WMF servers. Any hints, please? Was the codebase maybe renamed? Should this page be archived? --AKlapper (WMF) (talk) 13:24, 12 August 2018 (UTC)
