That train (USB-C) has left the station quite some time ago and Apple is still in the station, could certainly have done better.
And for moving to all wireless - unless you can get the losses down to <5%, bad move. Think about 100M iPhones charged daily and the loses add up to an enormous amount
It's nothing in the grand scheme of things. The impact of just how much more power hungry PC parts will get in the next couple of years would dwarf the extra power consumption of wirelessly charging iPhones.
I also have to charge my iPhone half as much as I had to change my last phone, because it uses so little power in the first place.
