How did you get from a mode 6 query to a log file?

a) the "real refid" is not being hidden.  The express purpose of the
refid is maintained.

b) if you have a valid reason for issuing mode 6 queries and the "other
side" doesn't choose to allow this, that's their policy choice.  In that
case you can continue to use them for time, or not.  Your policy choice.
