It's more than just that. The skateboard design for dedicated EV platforms makes for a better-protected passenger cell. Whereas before you had to dedicate all this steel into keeping the car rigid while mounting this heavy 250kg engine all the way up front, usually in front of the wheels (and plus all the attendant powertrain stuff), now instead a lot of that steel is dedicated to maintaining the integrity of the passenger cell, concomitant to maintaining integrity of the battery skateboard. As for why few companies put the ICE engine in the back, whereas front-engine layouts tend towards understeer, rear-engine layouts tend toward oversteer, which is a safety and usability issue for the 99th percentile of drivers (and that's after you put in the engineering to make it work). Porsche spent a lot of effort making rear-engine safe. The design also results in less room for storage.
