Re: [fetch] Can headers ordering be lessened? (#189)

No real use case on my side, although the fetch algorithm often uses headers get(), which is an indication that it should be made fast enough by browsers.

WebKit already has a headers structure that does not preserve insertion order.
This means implementing a new structure and regularly translating one into the other or vice-versa. A small overhead probably.

Lexicographical ordering would solve this although this may hinder some other cases?
