The problem I see is that there is no diference between a tail and a pair of arms. the composition is the same (muscle, bone?, tendon). And I suposse that Ojiro´s tail is so familiar to him that is like an extra arm/leg. There is no need to "activate".

I agree that separate the quirk only in three categories can simplify to much a quirk. A quirk, generally espeaking, is a mutation in your DNA (I guess) that produce variation in your cells. It is very complex and only three categories don´t seem to be enough to me.

I think I am beating around the bush. Maybe we see Aizawa using his quirk in this arc, and that can help a little.
