An uncontrolled intersection means yield to traffic approaching from your passenger side for intersecting roads of equal importance, or vehicles on the minor road yield to through traffic on the major road. Yield signs usually just formalize this implicit intersection control. Taking out one stop sign is usually not an imminent hazard to traffic, but taking out two from perpendicular approaches might cause a problem. Removing all of them would actually be slightly more safe than a bad configuration of signs. I expect my driverless car to be able to disobey signs when I indicate that it would be appropriate or necessary to do so. I may one day enforce this by carrying around two poles that bear "stop", "do not enter + wrong way", "no u-turn", "do not reverse + severe tire damage", and "no stopping any time" signs on them, and creating pop-up paradox traps for unwary driving AIs.
