I did realize that, then considered the fact that the FreeBSD version is 
pretty much the canonical ntpd target:

Running everything directly on the protocol's recommended platform, and 
with source code for everything, would make it very easy to document 
that the server is on spec.

OTOH, I have crashed head-on into some bureaucracies in my time, and it 
hasn't always been possible to make them see the light. :-(
