I'm here for a little bit besides my coffe shop stalking. I used it as a flashback feature to look into how my character got into the points she's at now when my Novel starts up.

If it's used for a super minor character is say go after it! Whoever is talking to you and you want to create a scene to explore them. So use it as a device to get an idea of the backstory and motivation of I'd say any character. Then for the antagonist one use it to see why this person is a human and their motives behind the whole bad guy role.
