I don't think it's useful. You can disable it:

  zstyle ':completion:*:complete:-command-:*:*' tag-order \
      'commands functions' -

I don't know why the default is what it is. I don't expect zsh
defaults to make sense. Why is interactive_comments disabled in
interactive shells? Why does prompt show hostname but not the current
directory? It's all for historical reasons, I guess. I do appreciate
that my shell doesn't break when I upgrade to a newer version of zsh,
so backward compatibility is a valid justification for all this.
