I guess you're right. The first three might even possibly get implemented by JK if somebody asks him nicely enough. The other proposals prolly won't be implemented unless others are granted access to the game's source code at some time.

What you won't see unless somebody else develops it, though, is a fully fledged scenario editor like Skirmisher likes to see. If somebody cared enough he could develop a third-party tool that takes care of the modding options.
