Well the depths/vestige/stigmas sound like things that would be more exciting to discover about each other over the course of RP - like our motivations, hints at the past, etc. instead of knowing from the get-go. 

Like, what if your character is evil but acts like a really sweet person as their cover? If everyone knows they’re evil inside or have a secret agenda, it’s harder to treat them sincerely and not metagame feeling suspicious, or trying extra hard not to piss them off. Just an example! *totally not evil what*
