Raphael, can I ask you a thing? You could maybe just add (or ask someone to add) a "zero-out transparent pixels" on the layers menu. This will make you possibly happy, and will NOT arbitrarily throw away data that is relevant to more than one group of users as this thread had shown. Maybe, if you want to be really picky and selfish about this - there are far more usability issues in GIMP as it is now - them instead of a menu option one have to actively click, there could be added an entry in preferences. Something like "Automatically destroy color data from transparent pixels". Or some name equally "warnfull" about what it does. With that, GIMP could be kept for Image Manipulation thats why we use it for. However, I would agree that such an __option__ - to zero out data pixels - should be added to the .png save filter.
