Are they not a problem because they tend not to form amidst late-game political tensions, or because you're strong enough to overcome them?I get locked out of war completely very often by defensive pacts if I'm small.
I think later in the game more than 1 is fine, around the time of ideologies big alliances aren't a problem in my experience.
If the former, then increasing the limit seems to just open back up unfun corner cases, and if the latter then it still prevents a civ going for a science victory from trying to disrupt a culture victory and other such strategic wars.
I just don't see what is gained, though I think the cold war resolution could be a good place to open it up because then it at least has political counter-play.
