I’m afraid you are incorrect. There are VERY few Poskim who agree with this Rema. This kind of speculation is part of the risk in Paskenening your own Shailos when unqualified to do so.
So, based on the Teshuvos printed in IGM, it is clear that he would have Paskened you may NOT ask a Goy to turn on your crockpot.
