As David has said I and others at my organisation would much rather include the leading 'A'. But we also wanted to make sure that we at least got the daylight savings abbreviation fixed.
Australians seem to have failed time and again over the past 20 years to get this issue resolve and I had come to the conclusion that a less preferred option was better than another failure.
However some very good arguments have been raised since I've posted my patch for the inclusion of the leading 'A' if a change is to be made. I'm more than happy to create a second patch for consideration.
