The worse thing with current Switch hack is removing the SDcard - then you have to reboot the Switch and do the payload thing. With a USB-C connection to the computer, data transfer can be really fast if there's a file transfer program that supports it - and no reboot. Wifi is just too slow for some retail games like Skyrim, LA Noire, South Park, etc... it will take literally hours to transfer them using Wifi.
Switch supports AC-wireless protocol so speed should not be an issue. I get 100 Mbps with my AC-router which basically means around 7-8 megabytes/second. Which is about half the speed of writing to my sdcard through computer. So getting a background process for FTP on Switch would be great.
