This is a very frustrating discussion.   Do you guys ever actually use  
DHCP in operation?   Connections aren't "forced to be renewed."   DHCP  
clients renew their leases periodically.   It's possible to set up a  
DHCP server to give out a lease that doesn't need to be renewed, but  
nobody ever does that.   Even if some random person at one site  
somewhere does it, they're not going to have enough clients to cause  
you trouble - it's only a large site that will cause you trouble, and  
trust me, they can't operate their network without regular lease  
renewals.

So in practice, for any significant source of NTP traffic, you are  
going to have DHCP lease renewals.   There aren't going to be any  
exceptions to this.

Furthermore, for clients that only do the lightweight DHCP protocol,  
there is a required refresh interval.   So again, this simply isn't a  
problem.
