One of the larger changes that would be nice would be to switch the APIs to expose header values as CharSequences instead of Strings. This would allow us to do matching without creating a String object and another copy of the underlying data. Since HttpMessage would have to go under drastic surgery to make that change it may be simpler to just have another implementation that is a little "rawer".
