Well, as far as I can tell, according to the current header
compression draft, there is no "static table". The header table is
pre-populated, yes, but those items would fall out of the header table
via eviction as the table fills. There is nothing in the current
header compression draft that says those items are permanent.... Given
that, and given that we've already established that reducing the
header table size forces eviction, setting the size to zero would
cause all of the pre-populated items to be evicted.
