Currently at this time not many hats have been changed. This doesn't imply that GST hats will be changed into accessories and it seems like some big assumptions are being made here.
Your feedback is very valuable though of course, please feel free to post other hats you would like to see turned into accessories or even constructive comments on what you would like to see different on this. I have old hats I personally wouldn't mind seeing changed. Change isn't always bad.
