It's kind of backwards.  NM expects to be in control of everything by 
default rather than to coexist with initscripts.  If it was, there'd be 
no ifcfg files.  If it sees an ifcfg file and it contains 
NM_CONTROLLED=NO, then it leaves the interface alone.

At the time udev runs, it doesn't have any way to know that an interface 
is controlled by NM unless someone has created an ifcfg file with 
NM_CONTROLLED=YES.  With no file there, creating a file containing YES 
would be useless because with no file there at all, NM will grab the 
interface anyway.

It's sort of a catch-22.  udev is assuming that ifplugd is the default 
because on MGA3 that is true.  NM is assuming that *it* is the default 
because that's how it was designed.
