I may be wrong, but up to now mode 6 wasn't standard in any of the NTP 
versions.  Maybe to have the right to change anytime.  Still 
applications may/do/will depend on it.

So an optional standard?

But you have to state whether mode-6 functions are required or optional, 
and while some mode-6 feature may be very implementation specific, the 
standard (if ever) should state which features within mode-6 are 
required and which are optional, and more importantly: How to figure out 
which features are supported.
