Google Contacts allows you to manage your address book, but look at that menu over there — what is the difference between "Delete" and "Remove from contacts"?

How is “Delete” different from “Remove from contacts”? Isn’t deleting the same as removing from my contacts? I tried Googling it but didn’t find a satisfactory answer.

Maybe selecting “Delete” will launch a drone strike. (If you’re in my address book, you’d better watch out.)
