The workflow you describe is not as unavoidable as you make it seem. I can plug my phone into my almost-decade-old DSLR, copy the photos over (and use the phone or even nicer a tablet as a larger extended screen), edit them in an app and directly share them through other apps if I want. If I didn't want the cable, I could get a WLAN-enabled SD card - or if I were to buy a current model camera, pick one with WLAN integrated, all major manufacturers have those now.

I would not want to edit photos on the camera, a phone or tablet is way more comfortable to hold for that.
