Moderately soon, I'll just give people a chance to read it and comment
first.

About as much effort writing on the TODO list as implementing. :)

Yes, this need to be done. It may not even be too difficult. But it still
needs to take into account that non-at-war units can quickly turn into
at-war units, ie we need to make some extra code for that. (that should
mostly be relevant for cities defence)

I think we should wait with attitude until we have basic ai diplomacy
working. I should then be easy to build on top of that. Until then the AI
could just use reputation.
