That may be so, but there is (obviously) a logical equivalent in how the separate partitions are logically presented as a single unit. I've tried some suggestions from the web which supposedly worked with the developer previews but don't appear to do so with the release.
For better or worse in the corporate development environment I interact with I have a need to be able to mount (or provide a link to a separate mount location) remote storage whose path begins with a specific name under the root. Not being able to do so is an annoyance at best.
