What benefit does the ImmutableObject attribute provide?

Question

I was testing the ImmutableObjectAttribute attribute just for curiosity to see if I could gain some beneffits applying it, or if it was just for semantic decora

Answer 1

From the ImmutableObjectAttribute Class documentation:

This attribute is typically used in the Properties window to determine whether to render an expandable object as read-only. As such, this property is used only at design time.

... so yes, this is only for decoration.
