Slug field: option to make field readonly

[JohannaPeanut]

Hi
We like to work with the slug field to have automatic slug generation. However, we have found that in certain cases (especially with collections, and when it comes to relations) it would be very useful to have the option to use the slug field as a read-only field.
Thank you :)

For example something like a readonly:boolean property …

slug?: {
  label?: string;
  generate?: (name: string) => string;
  description?: string;
+   readonly?: boolean;
  validation?: {
    length?: {
      min?: number;
      max?: number;
    };
  };
};
