well, to see the exact opposite of "cutesy", please fork homebrew and give all of those things GUIDs for names, including all the packages a user could install; you'll soon see why the names chosen are quite acceptable, indeed.
This is the worst straw-man I've seen this year. Realistically, non-cute homebrew names would look like bin, libexec, repo, that is to say descriptive names that are already in common use, not GUIDs.
