Would be nice if you could still make peace if you put a decent effort into it, being able to win them over if you will. Similarly I've noticed the AI tends to always side against you which can be a little odd, for instance the ERE attacked me (WRE) after their 1 village ally declared war on me and they had to pick a side, it was a little strange. They shouldn't side with a tiny aggressor over their giant friendly neighbor.
The imperium things a good idea but I presume you can still keep people on your side by giving them gifts? I used that mechanic a fair bit to keep the ERE on my good side last time, which makes sense given the historical context.
One last thing, betrayal is a bit tricky due to how the AI sometimes forces war. They often declare war on your allies to force a conflict with you, so they don't have to break treaties. It's pretty sneaky but they can do it without any real negatives. The real problem is that you're then forced to either drop your ally and lose trustworthy rating or start a war and lose your trustworthy rating. It's a lose lose all because you made an ally. If betrayal is a serious negative it might end up forcing the player to never make allies, as the cost would be too large relations wise.
