I agree 100%.

My recommendation is to

* NOT add the recommended no_cache lines.
* Instead use appropriate refresh patterns.
  ? and cgi-bin MUST match a refresh pattern with min age of 0.
  refresh_pattern \?      0 20% 4320
  refresh_pattern cgi-bin 0 20% 4320
* Use the recommended hierarchy_stoplist to avoid traversing a cache
hierarchy on cgi or query request.
