Hello WebKit!
We're working on an API to allow developers to declarative permit prefetch, and new prefetching which contemplates the need to avoid sending first-party cookies to other sites until the user navigates.
Mostly in these two drafts:
* https://wicg.github.io/nav-speculation/speculation-rules.html
* https://wicg.github.io/nav-speculation/prefetch.html
Managed as part of https://github.com/WICG/nav-speculation
Thoughts and feedback are welcome.
Thanks,
