Thanks for the ping. Makes sense to me for a user to be able to bar individual users (other than admins) from their user page and subpages. As I argued in my userspace protection RfC, user pages are not part of the encyclopedia, so the "encyclopedia that anyone can edit" argument for leaving them completely open (by default) really doesn't hold water from my perspective.

MZMcBride, the RfC specifically included a provision for very new users to be able to edit their own user pages. This was noted by the closer on the talk page. The task to enable that to happen was split off into a separate task, T149484 (not my doing or idea).
