What I'd rather see is a standardization of PD installed in houses. That is, as part of the electrical installation a high capacity PD power supply is installed, and USB C sockets available on all power sockets. It would be more efficient to do a one-off central supply.
The problem is, that PD supports many voltages, so there'd need to be some way to dynamically generate those.
But, a good DC house supply would be a good thing and easier to provide some kind of battery backup for.
