When was the last time you plugged your iPhone in to your computer? I don't think I've ever plugged my current phone in to my computer since syncs and backs up to the cloud anyway for me.
I haven't in years but everyone who isn't technically savvy in my family still does. I don't know if that's indicative of anything larger than my anecdote but I work with people who are very involved with technology who still sync all of their stuff, with a cord, using iTunes and their iPhone 6s / 7.
No idea how common this is but I feel like it's common enough that it should have been handled better.
