I don't think this is sensible advice unless NM is not working
on the desktop.
(Maybe that is what you mean?)
In my experience there are serious deficiencies with the network service.

How do you know these files have precedence, as a matter of interest?
Is that documented anywhere? 
(Also, if they have precedence, why do you have to tell NM to use them?
Or do you mean NM may change them if it wants to?)

How exactly do you put DNS in?
How do you know?

The main problem with NM is the complete lack of documentation.
For me, and I guess for most people, it works perfectly 95% of the time.
But on the 5% failures I have absolutely no idea what to do.
