NTP mode 6 packets are an OPTIONAL part of the NTP specification in
RFC-1305, and RFC-1305 even goes so far as to suggest that mode 6
packets be used only when other management and monitoring tools are
unavailable. Microsoft provides other management tools (w32tm, group
policy, event viewer, etc.), although they are barely sufficient.

As far as I know, the reference implementation and its derivatives are
the *only* implementations supported by ntpq. Some of its functions
are even version-specific and not mentioned in any RFC, right?

So asking you question the other way is just as valid: "Can any
implementation which fails to respond to "w32tm" commands be called
"decent"? Sounds silly.
