And its not like airliners need to do a whole lot of work routing aircraft around them. Just use the old routes from when the Soviets were kicking and you should mostly be right. China has made a bit more rules since then, but I think they are really the only other major country with weird restrictive airspace.
Note for Obsidian, there is a git plugin that can auto-push/pull from a repo. I put my repo on a server and have multiple devices use it as a sync feature (there is also a VPN to my home network involved). Not sure how well it works on the android app (its pure lazyness as to why I haven’t tried that yet…)
