If you don’t require it to replace cables it doesn’t need to. For adding some energy to the device while it’s on your desk or nightstand it works perfectly fine.
The efficiency issue is also exaggerated, phones don’t take much power to begin with. Anyone using AC or warm water for convenience is doing much worse in terms of spent energy.

I still fail to see the advantage of wireless charging. In both case a cable is involved.
