Hi TAG!

I'm requesting a TAG review of HTTP 103 Early Hints.

• Specification URL (IETF): https://datatracker.ietf.org/doc/html/rfc8297
• Tests: Plan to add WPTs once https://github.com/whatwg/fetch/issues/1225 is resolved.
• Security and Privacy self-review²: https://docs.google.com/document/d/1gCh_CnfrJq_VL7aGoq6skc7sn4yn5pKsM0gkHe5B9go/edit#heading=h.fhq04xt0tah6
• Primary contacts (and their relationship to the specification): @bashi @yutakahirano
• External status/issue trackers for this specification (publicly visible, e.g. Chrome Status): https://www.chromestatus.com/feature/4854144902889472

Further details:

• I have reviewed the TAG's Web Platform Design Principles
