[...] There are at least four differences between (in particular) ranges and a third-party library. One, there are some ranges-induced changes in the non-library portion of the C++ standard. Perhaps not very many, but some. Third-party libraries don't do that. Two, other areas of the library portion of the C++ standard are affected by having ranges. Third-party libraries don't do that. Three, ranges are part of C++20, so using C++20 is a necessary pre-requisite for using ranges. Third-party libraries can be compatible with, and usable in, earlier versions of C++. Four, by virtue of being part of C++20, if someone wants to use ranges then all the rest of C++20 comes along whether they want it or not. Third-party libraries can be (and perhaps even often are) independent, so they can be used (at least in many cases) without having to also take other language changes (whether in the library or in the language proper).
