The same was said about Compiz, but it turned out to be a passing gimmick that looked flashy but didn’t really add anything. Sure you could always make up reasons why it’s useful, I remember the same about Compiz, but… is it really? I could be proven wrong, of course, but it hasn’t been demonstrated yet.

It’s a solution in search of a problem. OP should have presented it with a real use case or benefit, not just flashy graphics, if it’s meant to be anything other than a fun oddity (which, to be fair, is perfectly fine).
