This would also sacrifice everything but the position and callsign. No
symbols (other than moving/fixed like the AvMap), and no altitude or
status text, including course/speed or weather data.
Speaking of weather data, for Garmin models that have enough custom
symbols, I think I'm going to devote 8 of them to wind direction arrows.
That way you'd be able to see wind directions (in 45 degree
increments) just by looking at the symbols.

Exactly. There's actually a firmware variant for the OpenTracker+
available that does 5 status messages based on some binary inputs. It's
used by a couple of taxi operators to show status based on a selector
