I don't think xattr works for folders. And you still wouldn't have the fancy presentation you can get with .DS_Store with the graphics and all that jazz.
Of course, they could rethink the whole thing but the point is that it's a legacy thing and at this time it's not worth dedicating much ressource to a solve problem just to remove some mostly invisible files (on UNIXs).
It's really easy to have scripts to cleanup for sharing to outside world, even some zip utilities do that automatically.
It can be annoying but it's really not a big deal, I doubt they could come up with something much better while still preserving the functionality and not making another complicated/convoluted proprietary folder format that wouldn't transfer any better to Windows...
