Not always. Male lions can't groom their own manes, and horses regularly
groom each other where they can't reach themselves. Perhaps some
structures can only evolve in a social context (solitary cats never
developed manes - even cave paintings of lone cave lions never show

As far as Microraptor (or any other "winged" dino) was concerned, I
suspect that aerodynamic feather fans would have co-evolved with
grooming ability by necessity.
