No, AH is split into several distinct systems -- an activated general, an outline draft general, one for China, two for India (indah-xx, indaho-xx), and one for Indonesia.
The Europe E-routes look like they're all in a single umbrella system like usaus.
Speaking only for India, it's partly to facilitate the overhaul of the AH routes I'm doing simultaneously with drafting indnh, indnh and, ind[sh]. We can visit whether keeping it strictly as indah or merging back to the general AH system once it's in a state where the placeholder tag labels have been solved.
