I think this situation is similar to Romania or Hungary Obviously the recognized alternative names and the official names don t have an equal status But the alternative name gained some degree of officialty by the governmental recognition B k ska aba is more similar to an official name than for example P kostolie but didn t became an equal alternative for B k scsaba You are right that these names are weaker than German names in S dtirol but stronger than not recognized minority names Because of their transitional status or quasi officiality I know that there good arguments against for their usage In Hungary I decided to change the infoboxes and no Hungarian user opposed this movement I announced it on the noticeboard so I think it is OK In Romania Ronline and Dahn did the same an edit war broke out but the majority of Romanian users accepted the new infoboxes Obviously I would like to change the infoboxes of Southern Slovakia according to the 20 limit you wrote but not at the expense of a major edit war
