I agree. I don't plan to share my workspace, and I think many would likely ever share their workspaces. I understand that many corporate environments could benefit from sharing, but a simple toggle for casual users would be wise.
I understand that it may be hard to implement since a version of it already exists. Still, perhaps a toggle between sharable and non-sharable workspaces would simplify and allow all non-sharable workspaces to use the same bookmarks.
