That would mean forcing Qi on all phones, this would have cost, size and material repercussions quite larger than using USB-C.

I love this idea, it made me wonder about the difference in efficiency between wired and Qi and apparently it’s not too far off: https://www.digitaltrends.com/mobile/state-of-wireless-charg...

Be careful what you wish for, once wireless charging is universal, they'll start removing the USB ports.
