I'd say it depends on how cold it is outside. The car will prioritize heating the battery over heating the cabin. So if it's extremely cold out and the battery hasn't been preconditioned you may not get much if any heat in the cabin.The whole "precondition while plugged in" thing is overstated, IMO. It's still electricity either way, whether it comes directly from the wall, or from the battery (that later gets refilled from the wall). Unless your drive that day is so long that you're pushing the range limits and really need to save battery power, of course.
If it's easy (i.e. you plug in overnight in your garage anyway), then sure, stay plugged in during remote/scheduled start. But otherwise, I just remote start the car about 5 minutes before I'm ready to drive it, whether [lugged in or not. If it uses 2 kWh from the battery to warm everything up, so be it. Just means it stays on the charger a bit longer at the next charge.
