No, I propose to not even bother with copper, if you prefer. Just use a
VLAN or any other type of virtual circuit inside those TerabitEthernet /
SONET / FrameRelay / whatever.

And do you propose to use dedicated fibers just for management? Or,
otherwise, how would you pass traffic to/from the copper switch, into which
you plug the fxp0 of a remote router? I bet in >99% of cases, connectivity
from NOC to the "OOB" switch shares fate with the connectivity to the
router, whose fxp0 is plugged into this switch. Not even mentioning that
this OOB switch is an additional point of failure with little chances to be
backed up.

So there is nothing in the fxp0's "OOBness", what is worth its clumsiness.
