Functionally, it's not an issue to have to deploy one or more slides to use the rig, as you say they only take a minute to roll in or out.
Some folks like to "stealth camp", meaning overnighting various places while looking like you are just parked. Truck stop, etc. Seeing a TC with the slides out is a sure sign somebody's in there. Or maybe you want to stop somewhere for a quick lunch and there is no room to extend the slides.
When we fuel stop, DW goes inside an uses the facilities and gets the snacks and beverages, I use the lav in the camper while the truck is fueling. When the tank is full, we are ready to roll. No room to extend the slides at a fuel island.
