Why should we make (unreasonable) assumptions about the specific configuration of a system, e.g. in terms of how are the different filesystems mounted? You know, "universal" means that basically everybody can use it for whatever their own purposes are, with a generous level of customisation allowed. We can't cater for all the possible combinations of /, /usr, /var, and so on, And BTW, why should we care at all? These are details related to *policy*, and *policy* should be decided (to the largest possible extent) by the user of a distribution. If having a separate /usr is a problem for Debian, we will try to find a way to get around that, and allow the users who want to have a separate /usr to continue to do so. The fact that almost nobody uses ext2 filesystems nowadays does not mean that we must strip the ext2 support from "mount", just to make another (unrelated) example. On this side of the GNU/Linux world, universal still means universal.
