To get the device created -- when attached to the pci card -- is udev the right mechanism?
I'm not clear if the problem here is udev, driver &/or my config.
IF udev, what specific rule would create a USB network device for the dongle, either with a wlp* auto-name, or if need be, "wlan0"?
Or, what else needs be done to init the wl* dev?

That chipset doesn't have a kernel driver.
There are a couple of available options:

The device can only be created if there's a driver to create it.

::facepalm::
well, it certainly help if I'd not just googled for ac1200 but ALSO paid attention to the fact I'd installed 88x2*a*u!
