This is a very big part of it. I wouldn't want this kind of practice in
general (not just ntp) to be regarded as 'normal'. Like you say, it's
not something you would want your ISP to do without mentioning it.
But this is already happening!
The "anycast" technique is similar to this, and is used for the DNS
service. When you
think you send queries to a root DNS server, in fact you are reaching
one of many servers
which is in your network area, not where you think it is. The root DNS
IP addresses are
specially routed.
It would be possible to allocate an IP address, e.g. 123.123.123.123,
and provide NTP
service on it in as many places as possible (ideally at each access
provider in the world).
Those that do not provide the service can route the address to a nearby
provider that does.
The effect would be that everyone can set an NTP client to use server
123.123.123.123
and get efficient NTP service.
But it requires cooperation from both providers (to set this up) and
clients (to configure
this address), and so it will not solve any existing problem. The DNAT
solution at least
solves a problem: that it is impossible to force anyone to take action.
