That's their choice. It's available for them to use. In the meantime
milions of servers DO support mode 6 packets while you have 0 servers
that currently handle this proposal. It's easier to set up those servers
to handle mode 6 packets than get them to do something else.

Well no. It's protocol neutral until you actually have to build this and
then you have to have something build into the NTP server to support it
and then it's no longer protocol neutral.

You then have a number of choices.

1) Interface your model with the NTP Server using mode 6 packets and
since it's already built into the reference implementation you get to
support millions of servers with it without making any changes to those
servers. None reference implementations would need to add mode 6 packets
and know what do with the requests that come in;

2) Build a Yang interface into NTP directly in which case you don't use
the NTP protocol at all and use TCP to do this. We have discussed doing
a separate management interface in the Reference implementation and it
would use TCP for this.

I have no idea what your intentions are. Have you also looked at the MIB
RFC for NTP? RFC5907 I think.
