maybe the (2,1)-category of dimensional theories is "abelian"-flavored as long as you don't use too coarse a concept of "morita equivalence", in which case it becomes more "topos"-flavored?? or something?? ... ??or is "morita equivalence" not so "drastic" here??? ???.....

??and what about "morita equivalence" in "dimensional analysis"?? ... ??...
