Quite agree that situational awareness is a good thing. But most situational awareness, I would suggest, is gained by listening in on the frequency and building a picture of what is going on. Although it would be nice, it really is impossible to explain every move you make to each aircraft.
I have found that when it is busy, the pilots with the best situational awareness are those who realise it is busy and don't add further to the problems by interrupting a controllers 'line of thought' with further questions. Of course every pilot has the right to query any ATC instruction but if it is busy dont be surprised to fine that the answer to the question "Where is number 1" is:
"Ahead of you!"
