I think the main objective here would be to reassure that the code base from the Apache Flex project stems directly from the Adobe code.
Being able to run it through the existing tooling is an interesting side effect that I was not considering but could act as a test case of sorts in order to perceive early on where Apache Flex would break or function differently with existing tooling. Other benefit would be that tooling vendors, Adobe included, could test Apache Flex early on and see what sort of changes were needed to make it usable with their producs. To the final developer it would be like saying: "Hey Adobe has donated Flex to Apache and to make sure that your products will work using Apache's version of Flex, here is an initial build from the donated code base. These are the thing that are different between the two (...), but this should not have a major effect on your work. Going forward and knowing these differences, it's your choice as to which version to use." Rui
