To be honest, cases like these are far from isolated. Sure, more and more devices such as laptops are starting to have PD input, but what about those that don't yet? Laptops are long term machines. Just because it won't be essential in the future, doesn't mean it's not a good product in the present.
I think we'll see another PowerHouse for those that have no need for AC power.
Just curious, what makes something like the PowerHouse so much larger than the equivalent capacity in power banks? Is it mainly just the additional outputs and display or what?
