fabricae were a unified logistical system connected to ancillary state organs, new states in western roman territory got their hands on maybe one node, it wasn’t very useful cut off from the other nodes. the notitia dignitatum even implies they were each specialized in one bit of kit. So even with the desire or determination to utilize such infrastructure, it wouldn’t bear much fruit, it’d be like seizing an ammunition factory when you don’t have a rifle factory or a train to deliver raw materials to make ammunition.
fabricae in the east, which we have no idea of the fate of, probably were more reorganized/privatized than lost altogether (i mean besides the ones they literally lost to the caliphate), particularly the Constantinople factory ordered by Justinian seems irresistibly related to the later armies/regiments permanently stationed and outfitted there, however the name and particulars might have evolved.
