About the feasts, I don't know if they are going to be added, but think how difficult it is to balance them. Swadia being in the middle of the map had more wars that others factions cause borders, they would loose settlements and morale, making a vicious cicle of feasting to gain morale while losing fiefs because of fests.
Feasts gather lords for easy access instead of map hunting, add options/events for socializing and getting quests and wooing ladies, ad atmosphere and make sense.
Still not having feasts is one of the biggest crimes the devs made. An unadvantegeous geographical location has no bearing on existence of feasts. It's not like Lords would be attending feasts with their entire armies - they would bring a personal retinue with them, and leave those to defend. And it's not like lords don't have retainers and second in command that can take up the defense while they are away.
basically:
1. feast is called
2. lord returns to his castle to leave troops, keeps elite retinue
2a (optional). his troops are formed into an army without a lord leader that patrols, and return to the castle when the feast ends
3. goes to feast
4. if strong enemy attack, feast is cancelled
Basically, no excuse. There's plenty of ways to deal with it.
