The problem with excessive unnecessary calls in a busy environment is that more significant calls may be over-transmitted. I have experienced countless occasions where two pilots have jammed the frequency on each other, sometimes with both starting and finishing their calls at the same requiring a 'two in together' broadcast to be made to be able to find out what either of them are doing.
Rather than blindly making every recommended call, developing a situational awareness of other traffic in the area and making appropriate calls will IMHO result in the lowest potential collision risk. There are huge differences between the type and density of traffic around different aerodromes, and unfortunately as a result the 'one size fits all' solution is inherently flawed.
