Maybe when we get to know more about Weiss' background, the butlers will be part of the story and become relevant.

And the Dust Shop Owner may come back when RWBY goes to From Dust Till Dawn to get supplies for a mission and we learn more about how Dust works from the old man.

Miles said that we are going to see the background of characters that we never expected. For example, Cardin's childhood, how he became a bully and why he hates the Faunus or Oobleck and Port days at Beacon when they were still Hunters in training or even the Malachite twins background, where did they learned to fight and why are they working with Junior instead of going to a school like Beacon?
