Multiplayer was really wonky before elexis fixed the out of sync, and there was, and still is a lot of work to do on the engine itself which is what most people tend to want to do and have the knowledge about.
I think mods are always a good reflection of what people want for the game. It's a broken one though, because it's usually one individual, but the motivation and time they invest in and the spread of the mod compensate for this. Those are features that I could definitely see in those mods, as they tend to compensate for the small gui evolution over the years.
Well if you have an actual working patch for it, then yes, if not no, this place is only made for code proposals.
