I'm not sure I agree with "rightly"; a sparse root zone had several advantages which have been lost such as disk footprint but more importantly, shared executables, libraries, etc. Cloning somewhat helps with the disk footprint, but the savings there will get lower over time as more and more binaries are upgraded. We clearly have to work on that. The memory saving of sparse root zones was nothing to sniff at.
