Those would be bugs, and bugs need fixing. But they can't be fixed if
they're not reported.

NetworkManager doesn't work in terms of interfaces, but in terms of
connections. I'll have to try it with a USB Wi Fi before I can answer
completely, but when you create a connection you get this option, and I
would think (and I'm going to try it, since I do have a USB Wi Fi NIC at
home, just not sure if it's supported by ELrepo or not) upon insertion a
dialog to create a connection will come up, and you select the option
from the pulldown in the IPv4 tab. The udev framework allows
connections to 'belong' to different NICs, as far as I can tell, and is
what makes the connection persistent across reboots in that sense. But I
reserve the right to be wrong.
