 * Test that the pool code properly replaces a server if it goes dark. (Not
   clear how to arrange this.)
 
-* ntpd is remarkably bad at standalone Stratum 1 - requires multiple chimers
-  (and multiple inbound NTP connections, and a hole in your firewall) even when
-  it has a known-good local timesource like a GPS.  This should be fixed.
-
 * Full support for NTS, once IETF has the spec ready
 
-* All the code relating to iteration over interfaces can and should be removed
-  in favor of binding to wildcard addresses.  Information on how to do this
-  us here: https://blog.powerdns.com/2012/10/08/on-binding-datagram-udp-sockets-to-the-any-addresses/

 * We could open only IPv6 sockets and allow them to handle mapped IPv4 addresses,
   as described at http://man7.org/linux/man-pages/man7/ipv6.7.html
