Those would be bugs, and bugs need fixing.

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.
