Should we file an issue related to the CORS question, assuming it's still an open issue?

There's an open PR on Fetch.

Might be good to open an issue to track this on our end as well though

This removes the Set <var>hintName</var> to "Sec-" concatenated with <var>hintName</var>. step from the request processing algorithm, which makes it reflect the current implementation in Chromium. However, I'm not sure if there are intentions for all CH tokens to have a Sec-CH prefix (eventually).

If so, I can do something slightly different and add some language to that effect and special case the set of "legacy" tokens (Save-Data, DRP, Viewport-Width, Width, Device-Memory, Downlink, RTT, ECT).

PTAL @yoavweiss, thanks!
