In theory, gpsd could do a better job of "blending" NMEA and

Is there any information in the NMEA stream that isn't also in the

Sadly, yes, but very little of note.  For example the startup NMEA
messages tell you things unavailable otherways.

Could you set a flag when you see binary and just skip any
NMEA if the flag is set?

No way to "skip", but just turn NMEA off:

   # gpsctl -b

Which is precisely what's been broken for about two months (in addition to the automatic binary switching).


   # ubxtool -d NMEA

Also broken. I haven't previously investigated the -e/-d NMEA/BINARY, but should include it in testing.
