I think the biggest problem here is that the working copy "root" doesn't necessarily equate to the project "root" or any logical root. So, someone could have checked out a sub-folder of a project and while that becomes the working copy "root" it isn't the project "root".

Tools like git and hg make it pretty obvious what the root of a project/repository is. Basically everything happens in reference to the root folder of the repository no matter what your pwd is. For example, a merge happens in the full repo not just the sub-folder you are in.

Are there any plans to have some way to indicate a "project root" in svn 1.7? Or, will it work the same way... we will know the working copy root but not necessarily the project/repository root. Having this might help with sub-tree merges as well as the relocate issue being talked about above.
