As we all know, any question on Meta should be tagged at least with one of following: bug, feature-request, discussion, support.

Nevertheless, I believe, there are some tags, usage of which automatically implies belonging to one of these categories. 

For example, retag-request is feature-request as well.

So my question is - may be, I'm saying only may be, we should think about something like 
tag dependency - when using tag A automatically means that this question belong to category B?

**UPD:**  Just want to note that I'm not asking about tag hierarchy on any stackexchange site, I'm talking about meta. As for rules, by which we conclude that this tag is depended to that on, I'm proposing very simple rule. If, say, tag have postfix -kind, then tag kind is parent tag.
