Not true. People ask how to add texture all the time and nicely textured walls can add character. No doubt any time you increase texture you add surface area to which dirt and other airborne things can stick but unless you are rendering hogs in the living room you can keep walls clean so long as you use a good quality paint store paint you can dust off and wash once in awhile.
I guess if you used dry mix/hot mud you could conceivably tape, mud and texture in the same day if you are experienced at the tasks. Coats of lightweight pre-mix compound will probably not dry fast enough though. Why the rush? Can't you alot 2-3 days or is their a schedule crunch putting the room back in use?
