Yes, the general gets a total summary. But in most situations, that summary is of no use at all. I don't care about the total army CS as anything other than a gross estimation of the army's overall health. What I really need to know is how much CS, and what type of troops do I have, in Region X? What good are troops in Firbalt if the battle is going to be in Iknopata? As it stands now, I need to beg for scout reports, wait for them to come in, then make the decision, then send a message to the marshals, then wait for the marshals to give the orders. All the while knowing that every minute the orders are delayed is CS lost because its not going to make it to the battle. If I had the information like I used to have we could short circuit all that and get down to what matters.
I really see no benefit to removing this information. It just adds frustration, confusion, and lots of unecessary busy work.
And yes, I know that if someone won't be marching with the army, maybe they shouldn't be in the army. But we all know that for every campaign there are always people that don't go for some reason, or fall behind, or get wounded. And getting lords to constantly move people around in armies is completely unreasonable.
In a perfect world, maybe this approach would work. But this is a game, and we're not perfect people. IMO this change adds nothing at all to the game except a bunch of unreasonable expectations.
