Any chance of this becoming standard (or “checkbox configurable” or similar)?
I really don’t want to fiddle with custom PHP if it can be avoided because I can no longer say “look, it’s all out of the box” … and it hides functionality for the next guy that admins the site.
WP itself disables stuff that has with structure/building the site to do, for roles like author and editors whom should only be concerned about content. WPSP should, as well.
