Thats the general idea. Although replacing the fixed level with
(Config.onoff.relaxed_header_parser <= 0 ? DBG_IMPORTANT : 2) would be
better and leave is configurable with the relaxed_header_parser direcive
(can be set to warn / on / off - default is on which is quiet).

warnings with the same noise problem.
