See https://github.com/whatwg/fetch/pull/585 for rationale and proposed Fetch Standard change. Please try to coordinate changing your implementation with others. It's unlikely to be disruptive, but still seems better if it all happens roughly at the same time.
Note: PR landed and test changes landed at https://github.com/w3c/web-platform-tests/pull/9911. It appears that Chrome and Firefox are planning to ship soon.

I'm finding a fetch call in iOS 11 not sending any cookies. Based on the user agent, iOS 11 uses AppleWebkit 605.1.15. What's the first version of webkit that has/had this change?
This fix went into iOS 12.
