Completely wrong.

I can assure you that we do run our own NTP servers, and our customer
routers are pre-configured with a Name not an IP address to get to them.
We let our DNS servers sort out the load balancing issues (if we ever
get any).

It's working fine, and several hundred-thousand clients can't be wrong!

No, the ISPs don't work this way.  I have yet to see many ISPs that have
demonstrated any capacity or interest in setting up their own NTP
server.  If they use NTP at all, in almost all cases they rely on
external NTP servers.  It is these same external servers that they would
plug into their DHCP servers (because they can't be bothered to run
their own NTP servers), and which would then be passed on to the

Which leads us to the mess that Danny is trying to help prevent.

I'm not convinced of that.
