It still is very confusing. openSUSE is as it is on the DVD and on the OSS and nonOSS and Update repositories. You may call this “official” if you want.
Everybody decides for her/himself what to install of this.
Also your concepts of “these packages which make it “out of the box” distribution” i a bit strange. At least I do not understand it. A distribution is a package of software merged together (starting with the Kernel) and that is put into “a box”, which is a saying from earlier times when you bought a box wth a CD (can still be done I believe).
A minimal openSUSE does not even have a desktop at all and not even any graphical software, But that is apparantly not what you mean.
