The observatory assets tarball would be different every time due to the version string, which makes it compress to a different size. The size changes would then move the program data around, making it much more difficult to determine if dart builds of different revisions are actually identical. Google Analytics doesn't need to know the exact version numbers, it will be fine to say they are bleeding edge builds of a particular version.
