[arch-dev-public] projects.archlinux.org - "Official" projects only?

Hey all, In a recent forum thread[1] someone kept suggesting they move yaourt development to projects.archlinux.org -- I was under the impression that was for arch "official" projects only, and I replied as such, but I'd like to make sure I have my facts straight. Can people like the devs of yaourt add their projects to projects.archlinux.org? Or is it for stuff like pacman, pacbuild, namcap, etc... only? Thanks.
