Fun, thanks for letting me know, will remove it :)

(I'll still stick with "I never really have run into a version issue for things I use Homebrew for, for places where it matters, I have whatever-programming-language-lockfile-for-the-project-I-am-developing" for cases where I need to be sure the setup is reproducible, which is why I've clearly never noticed this file was useless).
