If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.

(I restored my full quote above which I believe says this, though IANAL.) I don't see any option that means "this version and no other version". Is that your interpretation as well? And do we really need to distinguish between those cases in the portfiles? If so, I have to review all my portfiles, and other maintainers who were not aware of the distinction would have to also.

The rather straightforward third option is to specify a version but not
say "or any later version", in which case neither of these sentences
applies.
