... Can the region lord get an account of the food lost? ...
Indeed, just as there is now a notification of when and by how much the militia decrease, it would also be good to see how much food is eating by non-citizens (armies). While I do not know how the mechanic works for armies in regions, it would certainly wake up some Lords (and especially Dukes) as to how much food /other/ people are eating.
So a Duke might not want armies to rally in his city. But it saves the knights and lords money to do so, while costing the duke (he buys the food with his cold gold cash!). Strife. Conflict! Realms in revolt! Cities burning!
Okay, so I exaggerate
But it would add a new dynamic.
