Unfortunately, this is not easy to do. We document changes on top of other spec and we need to provide references. It would be a lot more work to refer to all different spec versions of C++. Also the development becomes more complicated as it needs testing and fixing against all different C++ versions. It makes sense to focus on one version and potentially provide an upgrade in the future. Also C++17 is a reasonable target most of developers should be happy with at this point.
