Although it is ignoring the generic type of the `Attr` key, implementors should take care to return values of the correct type, and return null if no specific value is available. For public consumption of attributes, prefer using `scan(Attr)`, which will return a typed value and fall back to the key's default if the component didn't define any mapping.
