You can use favors/trust to inform an ally to not start any wars in a short timeframe so that they can join your wars and better prepare (do they actually? never actually use this) But I don't think the AI ever uses this function.
The AI never uses favors to get the trust higher between a themself and a player nation.
It would really be great to have the AI use this function better, to inform you of upcoming wars they are planning and want you to aid them in.
I imigine this can be exploited, but that can easily be outdone with - when they inform you, you can either say yes or no. Depending on whenever this is a thing. Before the call to arms you are not allowed to delete them as your ally, to avoid this war. And if you refuse (if you say yes) You get an stab hit? and lose more prestige (but that's really not a big issue, and never were.) But this is not something for me to decide or think of.
In any case - the trust/favor system is a paid feature, and I wonder why it isn't in the game? A certain AI personality can even warn you (somehow) before they declare war.
