in my opinion no because the object index is prone to changing whenever we perform an operation on the object(like removing ,re-arranging)which makes it "not unique" with the rendered child.
if no id is specified,you could use another property that remains constant regardless of changes made.

Interesting, nice read! Got a question though, what’s the purpose of the key property on a component, you didn’t explain that but I see you used it.
