Right thanks for catching that! Maybe we want this to be `default y` so that we do not change current behavior and platforms can opt-out as needed instead. Inline ECC should not be default behavior on our systems, rather those who need it opt to enable it; since it significantly impacts boot time on systems with large RAM. So I think we should keep it as default n.
