Thank you. Hopefully this patch will be commited soon.

I'd also like to make an additional, unrelated, suggestion, specific to
10.2 upgraders:

I have been using ntpdc(8) for a very long time and unfortunately
ignored ntpq(8) yet, so that it took me a significat ammount of time to
find out why my 10-stable -> 10.2-Beta2 update suddenly stopped talking
to me like I'd expect...
