The function SpecialPage::getLanguageConverter does not use service injection and it seems not useful to inject the factory into every special page when not used on each special page or used from code directly in the SpecialPage class. Bug: T259960 Depends-On: I550f2db0c652193755ad4ad04cececad00be72ea Change-Id: I11e5d67b7051c159b8d32bf056a0e24aa3b526ae
