If I remember correctly, I suggested having "ghost" tag before (or someone else suggested and I approved it), but it has been overruled. Though maybe now this decision might change
I'm not sure about the hidotama tag. I believe we could just make "ghost" cover it instead. If we want decide to make it however, I believe it should be as a child tag of ghost and not created separately.
As for archery vs. bow and arrow - while I agree it could use a change of the name, I also agree that simply naming it "archery" is not ideal name. At the very least I would prefer "archery", because it seems to cover more. What I mean by it is that even though we agreed to use "bow and arrow" in situations where either bow or arrows alone are visible, the name itself contradicts this, while "archery" could be more naturally used to describe anything related.
