This question brought to my attention that, as of 2 months ago, there is now an airbus-a319 tag. It has exactly 2 questions and no tag wiki. For nearly all, if not all, other aircraft types, we do not have individual tags for the different models, even across different generations.
Is there really a need for a separate airbus-a319 tag or should we just retag its two questions with airbus-a320?
