My logic is: 1. Apache Royale already changed the namespaces of mx and spark, so there is not reason to do do the same here; 2. It's seems that it's the last rest of piece of code (one line of code per mxml) with reference to adobe; 3. We should get rid of adobe, flash, air, swf and swc from the project as much as possible (not for me believe me and I don't have nothing against flash/flex, on the contrary, it's because of the negative around it); 4. For last but not least: 2008 it's old :P for a namespace on a new project even if the specification didn't changed that could be weird change the year.
