Not compressing headers is simply a value of zero in the
compressing-headers space. We cannot know that there will not be a
better header compression algorithm developed tomorrow, and we shouldn't
prevent such an algorithm from becoming a de facto standard. If you
grant that header compression may take more than one form, it seems
logical to allow no compression also since there may be use cases that
support it.
