Some kicker / labels are very technical in nature and not ment to be edited by GUI. Being able to set those kind of kicker/labels to readonly would prevent the problem of accidently changing and potentialy breaking the workflow of an story.
Use case:
data from a third party system is being mapped to a story via a kicker/label.
The data is only consumed by another third party tool that reads the story data via IFX/Story-API
