I'm surprised that the author doesn't see modern usage of coined names, maybe we read different things. It is very common in almost all of Pynchon's novels. Vonnegut used it often as well."Benny Profane", "Oedipa Maas", "Pierce Inverarity", "Malachi Constant", and half of the characters in Gravity's Rainbow: https://www.coursehero.com/lit/Gravitys-Rainbow/characters/
