No, it's not intended, and I just found and fixed that this morning.
All WWAN pseudo-ethernet interfaces should have DEVTYPE=wwan set, and NM
should handle that correctly by not creating an NMDevice subclass for
the WWAN interface, but by subordinating that kernel interface to the
NMDeviceModem that was created in response to ModemManager finding a new
modem.

If you try git master now, does that fix your problem?  The fix is
commit ead39cb42174e84d4054692814098f1bab8a7913.
