     description: |
         This value controls the maximum number of bytes (in KB) the gorouter will read
         parsing the request header's keys and values, including the request
         line. It does not limit the size of the request body. Requests with
         larger headers will result in a 431 status code. Must be between 1 and 1024kb.
-        Note: This value takes precedence over router.max_header_kb but has no default to not break
-        existing setups. If you previously configured router.max_header_kb it is recommended to
-        switch to this property instead.
