Empty user pages were red-linked before UCP too. The difference is that legacy wikis have a welcoming automated tool which leaves a welcome message to any new editor and creates a default userpage with placeholders. UCP wikis don't have such a tool yet so the userpages of new users remain empty. They can edit them, or you can put some placeholders for them as an admin.
