Discussion Best way to implement readonly fields for ScriptableObject data

I don't know if this is really an improvement or something worth changing, but I noticed something subtle while snooping around the ScriptableObjects for storing data. For example, refer to around line 97 here:
https://github.com/UnityTechnologie...ct/Assets/Scripts/Dialogues/DialogueDataSO.cs

I used to use that same approach (also described in this thread) to make values that can be set in the editor but read-only to other classes:

However I saw an even shorter approach in this thread:
https://forum.unity.com/threads/serialize-readonly-field.426525/

In there, it's pointed out that you can accomplish it with this syntax:

Code (CSharp):

1. [field:SerializeField] public int Id { get; private set; }

Ultimately that amounts to basically the same thing (using the automatic backing field, instead of explicitly declaring one) so it's kinda just interesting trivia at this point.
