Let me remind us all that we intend to toss pure space soon. So let's not build any new features on what pure space means and does, certainly not for such marginal use cases. We don't want to take upon ourselves any jobs that might prove difficult to keep doing when some of the underlying infrastructure changes, because it would be ridiculous to have this little tail wag the Emacs dog when the time comes.
