The big one my wife champions is the idea of a porch or transitional area. If outside is muddy and the sleeping bags are not, you want a space to leave your dirty gear or, even better, a place to get changed out of your gear. Slipping out of armour and untying your weapons-belt is fine, but things get more complex when you need to remove muddy trousers without a) dirtying your sleeping area and b) flashing the neighbours.
Our OOC tent has an enclosed and porch without a groundsheet. All the windows can be covered with integrated blinds, so we can strip down to underwear if we have to. It might not be too warm, but it’s private enough.
Our IC tent is a 4m-diameter bell tent. That means no porch, but it’s big enough to have three of us sleeping in the back on a thick rug while still retaining a space at the front with a coarse mat (like you might have in your house) where you can strip off in private and wipe your boots.
If I am honest, cooking is the hard part. Never cook with gas in an enclosed space! You can usually cook outside your tent (if you are careful), but have a back-up plan for what to do when the rain is coming down in sheets and the gale keeps knocking your windbreak over. That might be communal cooking in a large faction tent, but it might as easily be the onsite vendors.
