osx can do this because "osx" is about as specific as "Ubuntu 20.04 LTS", so 90% of the problems that were described in the article wouldn't happen because there aren't many osxes. I personally don't use it, so I can't tell how good the story is with 2 different versions. I've heard lots of upgrade troubles from mac users when a new OS release comes out, but maybe the authors are usually better in keeping a version for current-1 around, or the latest version compatible with current-1? Then it's still only 2 versions and not 10 distros.
