"The simple fact is that a well squared away pilot is the type who already gives substantial radio calls when in or about a CTAF"
Giving substantial radio calls on the CTAF is not always useful. What's wrong with underdstanding and making the required calls and only making additional calls when required for traffic separation?
There are still far too many pilots making half a dozen inbound calls, then responding "XXX copied" to every broadcast from every other aircraft...
