Re: [fetch] Why are headers a special data-structure? (#154)

The spec is written so that headers are all ordered in the header list by their insertion time (at least request headers).
Ordering headers with the same name makes sense.
What about the ordering between headers with different names?

For instance, should iterator retrieved from Headers provide access to key/value in the insertion order?
If a web app sets a request header (A, 1) and then a request header (B, 2), should the corresponding HTTP request try to keep the same ordering?
