While I making a custom package. I found if i can let the generated ScriptableObject asset has its own icon, will be cool. In general develop, it can be done by adding the namespace/to/Scriptable icon.png to Assets/Gizmos. So, I thought the custom package folder could include the Gizmos? And i found the office package include the Gizmos folder! But it has no effect, in my custom package... Any thing wrong, or it is no support now?
