I think you replied to the wrong node in the thread. I think what you
are actually doing is telling Steve that he shouldn't be asking for
these changes to included in ntpd at all.
Also, I don't think Unruh's position is clear to many of the regulars;
they are simply using it to promote their standard positions, whether it
be joining a developers' group, or not using Linux.

The impression I'm getting is that extends beyond local networks to
include most sources that would be used by fixed, land based,
installations, in the first world, at least.

Long term wander is easy to cope with, unless you run out of adjustment
range. I don't see why chrony should have any lower a limit on that
than ntpd's. On the other hand, the evidence is mounting that chrony is
much better at handling non-random diurnal wander.
