Nice thread.

A small nit: I fly a low-wing, and any ATC traffic alert inside of 4-5
miles
and below my altitude will be hard to see without some maneuvering to
remove
my airplane's nose or wing from line-of sight. I expect even a high-wing
will also have at least the problem of traffic under the nose. I get a lot
of these alerts, where the traffic is a thousand or more below me, often
unverified, and I find them useless.

You might want to think carefully about the potential impact of erroneous
mode C information. It happens. It has happened to me more than once (see
earlier posts). It has caused me to pay attention to those "low and close"
alerts by at least for a moment, pretending that it is at my altitude. At
least it gives you something to scan for. Maybe you'll see that glider
loitering at cloud base.
