Realistically adding such features to the game would require so many rather difficult to program layers of complexity and depth, ahead of other much more lucrative and promising fixes, that it's probably not worth it. Needless to say it would require a full-blown diplomatic system the likes of Alpha Centauri, and probably even more complex than Alpha Centauri to get all the options you're wanting, and given the nature of this game that is not the most important thing, and given the nature of the additions and the engine they'd have to fit into it would be quite time-consuming and possibly rather difficult to do.

How about I just assure you that having such a system in place would only open you yourself up to the same sort of thing, which could be quite aggravating (as it has been for me in dimplomatically complex games with similar features), so you're probably not missing much :-)

But the main thing is that there are much more promising issues (in my opinion) to work on now.
