Of course, but my idea of interesting is unlike yours...

Don't let the far future block the present.  I need -4 and -6 for the
NTP side of an NTS connection to do testing.  And long term I would want
-4 and -6 independent of ask/require.

Why?  Well, my IPv6 connections have much less latency and jitter than
my IPv4 ones.  Without -4 and -6 on the NTP part of NTS I can't make
those comparisons easily.
