W.O.G.
A superb summation.
If we take the proposition by Jetski et al that there is no risk of a collision, at least it gives us the opportunity to read the Herald Sun or Australian en route.

So an aural traffic alert in a GAAP won't stop midairs? I'll let the towers know, they too can read the newspaper.
To continue the W.O.G. proposition, I fail to see how adding an EXTRA layer of safety, that reports directly to the PIC without third party need, is a negative.
In aviation safety the chance of a midair is - as Jetski pointed out - miniscule, although increasing nearer the CTAF. It's the consequences of the midair that make mitigation worthwhile.
