I don't think dumped is the right word here. My take is that Third Wire either supports a game or not. There is no in between. And it is primarily because customers do not understand and do not accept half-support, but they surely understand unsupported. As soon as TW openly shows a limited support for the SF2 games, like a Windows 10 update, there will be customers complaining he does not support it enough.
Also I have some things I could write down here as bug-fix wishes, but I just get cought up in my memories of the last years of SF2 development, where TK wrote how things should be simpler instead of realistic. Game and not Sim. IIRC he at some point suggested automatic landing gear up instead of manual. Then there were many complaints about missile effectiveness in SF2NA which was addressed by making player missiles stronger then AI missiles in June 2012 level. I am on May 2012 level because of that.
I do not blame TW to have priorities that differ from my wishes. I think TW priorities were at that point not personal anyways, but about customers and sales. Or maybe they were personal a little, because the original course was just to hard for Devs. Modders and bolt and nut counters make very annoying customers already, but when beyond that there are not enough sales with increased costs , then one has to change course.
With that in mind I can only imagine some small patch for SF when it is totally clear that it does not imply much, and it is just for fun. But wheter or not it is fun for TK, no idea. It is not my business either.
