I don't think it's as cut-and-dried as all that. During his time at Marvel, Hickman has gravitated toward characters who pursue their missions at the expense of their human side, people like Reed Richards and Tony Stark and Dr. Doom and Evil Reed Richards, but not to the exclusion of more identifiable characters. His Spider-Man is warm, but more low-key than usual; we can see him struggling to put on a brave face for the civilians in Secret War, and his presence dilutes the gloom after Johnny Storm's disappearance in Hickman's run on FF. The done-in-one stories during his Avengers run give us relatively expressive backstories for characters like Smasher, Hyperion, and Starbrand. The emphasis is on grand schemes and big ideas, especially in New Avengers, but it's not quite fair to say that the human element is shoved into the distance. It might look that way because Hickman expresses character through plot more often than he deals with characters in Bendis/Whedon style throwaway scenes. It's a given that Secret Wars #1 is not a character-oriented issue despite a few nice character beats; almost everyone is displaying selflessness in the face of almost certain death, which doesn't exactly make for a diverse emotional tapestry, but it fits the story he's telling in this first issue.
