Yes because wireless charging is still very inefficient. Most of the energy seems to go into cooking your phone for you rather than actually recharging the battery.
It's fine for a quick top-up but if you want your phone to go from flat to 30% in 15 minutes you're going to need wired charging for the foreseeable future.
Going over to full wineless charging would have been very anti-consumer. Not that I'm going to get an Apple device, but I'm glad that they didn't try and screw people over on that one.
