Just that, really. Planning my new kitchen at the moment and every magazine/Houzz image I look at integrates the kitchen and dining room, and maybe even the living room too. I easily could knock the kitchen through to the dining, but I quite like a separate dining room. I also like a separate living room. I like to be able to close noise/smells off in different areas. But thinking ahead to a possible future buyer when I move on, will it be a wasted opportunity if I don't do the whole open plan thing now while I can?
