Not sure why you think it will increase the tow capacity in the US..:it’s not a lack of power, it’s the weight that gets maxed out.
I think that it would be more accurate to say that most vehicles with their maximum tow package get maxed out on the weight. A lot of pickups don't have maximum tow package and are drive train restricted. I believe that a lot of SUVs, minivans and even cars would fall into that category. All of these would benefit from having a trailer that puts less strain on the tow vehicle. An F150 with the base engine set up for fuel economy might be able to tow a decent sized trailer with this package. People who buy 4wd for trailer towing might decide that might decide that having a driven trailer axle would serve the same purpose and return a lot better fuel economy while doing it. The $4000 savings for 4wd would go a long way towards paying for this feature. I agree that it is not a cure-all but if affordable it could help a lot of people. The key is going to be price but costs in this field are falling rapidly.
