An alternative perspective would argue that an Android device without a boot breach is already as locked down as it can be, and that the same breach on Fuchsia

An alternative perspective would argue that an Android device without a boot breach is already as locked down as it can be, and that the same breach on Fuchsia might give a much easier path to mix and match unchanged components and custom implementations. I don't know which argument carries more weight. Should we expect Fuchsia to take a defense in depth approach to component authentication?
