One good use for this is integration with an abstract asset system - it’s been a massive help to artists to have one common widget to display the name of the current asset (character, costume etc) without needing to worry about navigating dcc-specific file structures to find what they need.
If you have the same UI across Maya, Substance and Unreal, all those UIs can display “character: hero1” and you know that all your work is going to the same destination
