I initially said that too, as I used to use it myself, but I can confirm that despite it being used in blizzard code, we can't seem to use it in our addons. I have done several world quests, emissary quests and regular levelling quests and it never triggered once at all today. So maybe they have it in their code still but it never triggers either. It's not like they haven't left redundant code in there before

elseif ( event == "QUEST_LOG_CRITERIA_UPDATE" ) then
    local questID, criteriaID, description, fulfilled, required = ...;
 
    if (QuestMapFrame_CheckQuestCriteria(questID, criteriaID, description, fulfilled, required)) then
      UIErrorsFrame:AddMessage(ERR_QUEST_ADD_FOUND_SII:format(description, fulfilled, required), YELLOW_FONT_COLOR:GetRGB());
    end
