I mean yeah I barely use cables to transfer data, but there are times I need to plug it in to back up files. The Pixel 7 Pro is also a bar of soap and slides off of my wireless charger, so it’s more reliable for me to use a USB-C cable. I also like having the phone next to me in bed, and so I use a USB-C cable.
It just seems odd to remove something that is so reliable, even if only to have as a backup method. It would only make sense to remove it if wireless chargers are the dominant form of charging devices, especially in a portable manner.
Having a port also enables things like game controllers and wired headphones, if the user chooses to do something like that.
