Sorry, but you misunderstand what asdf is! In Homebrew and Hermit and others, somebody needs to create a PR to add support for a new version - with asdf, it's not necessary and it's always ahead of Homebrew and other package managers, because it directly polls the releases of a project! So, you're not a the mercy of a packages repo maintainer! I've considered Hermit, but many of the tools I needed were severely outdated so I gave up on it!
