One thing that I'd like to specifically ask everyone to consider
is the intended future of the alternative port. Do we expect NTP to
fully move there at some point and keep the port 123 only for legacy
implementations? Or should it always be just an alternative in case
the port 123 is not working?

The current version of the draft says the client SHOULD start with the
alternative port. If we don't want it to become the standard NTP port
in future, it might be better to start with 123.
