Adding code to allow enabling or disabling this output on the fly would
work MUCH better (as an example, see "rndc querylog"/ options "querylog
[on | off ]").

Adding a "well, we needed this one time" value to the middle of a
long-standardized log file does no customer any good and inconveniences
everyone.

You own the code and can do whatever you want to, but I'd recommend
making the default log message what it was prior to 9.10 and adding
additional fields via pre-configuration and "rndc".
