Maybe run a small discussion on the ModemManager list first?  This would
be the first non-QMI device there, and I don't think userspace is
prepared for that.... 

I expected this type of device might exist, but we haven't really tried
to support it before (AFAIK).  Although the qmi_wwan driver doesn't care
about whether the embedded control protocol is QMI or AT or something
else, current userspace applications do.  I am not entirely sure about
how this should be handled, but it should be sorted out before we start
adding non QMI devices to the driver.
