To be honest, the "option" that I chose when playing single player games, especially when I went through a phase of playing 8 player escalating was to foe one of the two people that were systematically teaming up in those types of games. It works. If both of them can't join, then you have less reason to worry about truces. You should definitely do the same if there are specific people doing this on a constant basis on the settings that you like to play.
I do not like truces, I don't truce. One of my regular team mates actually liked this kind of diplo, but I didn't. It kinda goes against what I feel is fair play, but meh. If other people want to play like that, I don't judge, I just don't want to be in a game with them.
To make it an option, you would literally have to make written truces illegal and I'm not sure it's something they'd introduce. If they did, it would have to be done in a way that is fair to everyone. I can't see it happening, but if it did, I see it working something like this:
Add a truce button to the game. Make it so that both players have to press it to activate the truce and they literally can't attack one another. Truce only lasts for two rounds and after that, they can attack each other again. Once a pair of players truce, they cannot truce again making it so that no two people can team up for the entirety of the game.
I think the problem with trucing is not necessarily that people make agreements, it's that people tend to keep those agreements going until one of them breaks it, despite initially setting a 2 round truce... it often goes on forever. I've seen this happen time and time again.
