// TODO: we currently default to Some(NoReferrer) instead of None (i.e. unset)

// are currently unimplemented, and so in such cases we may be ignoring the desired policy.
// If the default were left unset, then in Step 7 of the Fetch algorithm we adopt
// no-referrer-when-downgrade. However, since we are potentially ignoring a stricter
// referrer policy, this might be passing too much info. Hence, we default to the
// strictest policy, which is no-referrer.
// Once other delivery methods are implemented, make the unset case really
// unset (i.e. None).
