I think the high command (outside of the branch chiefs) doesn’t literally represent the high command, but rather adopting the strategies and ideas behind certain leaders. So by appointing them the flavor is supposed to be giving up control of the army towards certain officers away from you the player.
Personally though I wouldn’t mind if the system was tweaked so you at least had some command power left over even if you’ve got a large command staff
