Hi The gotcha is not on the manufacturing end. When you show up with a dual ground pin part, the OEM asks: Where do I tell the PCB layout guys to put the other ground? The answer always comes back to “there’s only one ground plane, they will both connect to the same plane.”. If you get past that, the somewhat surprising next layer is that temperature performance maybe isn’t that big a deal to them ….
