Huh? Homebrew supports and frequently uses dependencies between formulae. It’s a bit janky around upgrades in my experience, but you’re going to have to clarify what you mean.
Dependency management means the ability to have more than 1 version of the dependency installed, under the same package name.
i.e. Let's say you install a bunch of homebrew packages, everything is working. Then 6 months later you go to install another package - homebrew likes to upgrade all your packages (and their dependencies) willy nilly.
And if it breaks shit, there's no way to downgrade to a specific version. Sometimes shit broke because the newer package is actually a broken package, or sometimes it's because the dev environment was depending on a specific version of that package.
There's basically no way to have multiple versions of the exact same package installed unless they use their hacky workaround to create additional packages with the version number included in the package name.
