Since it's packaged as the default from the upstream vendor
distribution, and since the "system-config-network" tool from the
upstream  vendor provides no ability to access or manipulate this
feature or numerous others, and since they elected to use
NetworkManager as the default configuration toolkit for the anaconda
installer and other tools, I'm afraid it's clearly their
responsibility if not their fault.

And ignored *every last one* of Eric Raymond's published guidelines
for open source GUI design, much as the Gnome crowd does on bad days.
The software is feature driven and rejoicing in showing off "oooohhh,
look at all the stuff I can do", very little of which is of any day to
day use and most of which actively interferes in normal operation.

There are compelling reasons I like to build and use "vtwm", from the
Penguin Liberation Front, as an extremely lightweight window manager
and to disable NetworkManager with an ax.
