I don't think anything is missing, but you don't get it all in one package.
click ( http://click.pocoo.org/6/ ) has a lot of this stuff in one package, but not everything, eg. composable command lines, progress bars, spinners, prompts, bash completion, colors, paging, launching common applications ($EDITOR) 'n stuff like that.
pyinvoke has a somewhat different focus, but also quite some stuff similar to this.
+1, would be great to have something like that as an integrated toolkit on the Python (more specifically, Python 3) side. I currently use tqdm for progress bar, but it'd be great to also have a spinner and the rest of the goodies.
