I hear you.

Sadly, past experience taught me that NetworkManager is the Wave Of The 
Future™; and all alternative ways of getting things done will, very likely, 
stop working at some time in the future.

After some hacking, it looks like dhclient-script is simply not used at all, 
when NetworkManager is running the shows.  When invoked from NetworkManager 
(via dbus), dhc_dbus is a hardcoded constant 31.  So, the first two nested 
if statements in dhclient-script end up sending the new interface 
configuration parameters via dbus again, and the script immediately 
terminates.  It looks like NetworkManager is the intended receiver.

And it looks like that NetworkManager, as of now, does not support the 
"ntp-servers" and other DHCP parameters.  Of course, I have to figure it out 
by staring at the code.  I could not find any useful documentation to help 
me figure this out.

So, rather than letting dhclient-script handle things that are not yet 
implemented in NetworkManager (which appears to be the purpose of the 
dhc_dbus variable), everything gets simply turned off, and NetworkManager 
just ends up doing the few bits it knows how to do, and drops everything 
else on the floor (even though dhclient-script could've easily handled it).

That makes sense.

Not.
