I am not sure the care/don't care is a player divide. Some players can "not care" most of the time and then, suddenly, one of them asks "how can the cave we are in can have a access to the sea, since we just went down X feet, and the cave entrance was Y feet above sea level? We should be submerged right now..." I retconned the length of the shaft they climbed down immediately so they could be at sea level, but I did'nt expect them to have tracked the depth they were at. It was totally inconsequential at the moment, but you can have perceptive players just throwing a remark and threaten to break suspension of disbelief. If you're designing coherent architecture every time, you'll be less prone to make a blunder. Not that it's game-breaking in any way...
