Perhaps I am misunderstanding what can and cannot be

the DAG matters a lot to some of us. Consider:
Cellular organisms
Archaea
Bacteria
Eukaryotes
Animals
Vertebrates
Invertebrates
Plants
Fungi
etc.
These are not correct taxonomy terms, but just for example. How would
these be represented? With categories, it's straightforward. I don't
see how a flat tag intersection does this.
I don't think there are any plans to remove subcategory functionality.
Only unnecessarily specific categories will be ditched, presumably,
that logically consist of nothing more or less than an intersection of
other categories. Categories like "Plants" don't, so they'd stay.
