User demands for performance, features, will compel there to be always a need for the fastest possible charge. No escaping that, if you go with a bigger battery, it takes longer to recharge (so you want fast charging), if you go with a smaller battery, you need to charge more often (so you want a fast charging).
(and why I think Apple who do not use Qualcomm chips will be compelled by logic to embrace USB-PD for iphone which goes upto 100W)
I think the key to wireless charging is its cost, it is very low cost ($5?) so a "why not" kicks in. If you're looking for differentiation then wireless charging is easy and cheap.
The issue over last few years has been the move from a plastic outer covering to metal, that blocks wireless charging (and NFC) and so external antennae bands to get around it but that doesn't help wireless charging as you need a round shaped big EM transparent back. So you can do glass (ceramic), or plastic.
The case for wireless is less now with USB-C.
So wireless charging is a "why not" which is useful, but I'd not redesign the whole product around it.
