We've discussed using ttys for GPS on MBIM devices (since MBIM does not handle GPS) but I don't believe we've implemented that yet. We might also want to implement the Signal API via AT commands on MBIM modems that don't support AT&T Device Services, but that hasn't happened yet either. So for modems that MM drives via QMI and MBIM, ignoring AT ports should be OK for now.
