I'm mostly a Fw190 driver and fan, but sure, count me in. If i was to make a simplistic analogy, i'd say that simulated fights in these planes would be like having a hot-rod version of WWI biplanes and that makes it fun and appealing to me.
As for possible objections from China, i think the issue rests on how easy it is for a disagreeing party to take legal action against you. It's just like the Grumman vs Maddox Games situation:
If you are a company releasing a commercial product, they can threaten with lawsuits and force you to settle or accept their terms out of fear of legal expenses, or take legal action to have your game banned in their country and cost you sales.
If you are a bunch of non-commercial 3rd party modellers however, they can't individually sue you for exercising basic freedoms in your state even if they tracked you down (at least not without causing a diplomatic incident with your government and giving free public image ammunition to their rival governments in the process, ie not worth the trouble). The most that would happen is they would block the download of your content in their country, but that wouldn't cost you anything as it would be free anyway. If anything, it would save you money in the form of reduced bandwidth/hosting costs not having 1.2 billions of people as potential downloaders of your community add-on
Hence, if it's done by people that can't be blackmailed or have their arm twisted by a combination of legal and economic means, there's nothing they or anyone else can do.
