I understand; I was concerned about this case:

$ PS1='\n\w$(__git_ps1 " (%s)")\n\$ '

/home/rhansen/projects (dotfiles)
$ GIT_PS1_OMITIGNORED=y

/home/rhansen/projects              <-- Git prompt goes away as desired
$ cd foo

/home/rhansen/projects/foo (master) <-- Git prompt back as expected
$ echo ignored/ >>.gitignore && mkdir -p ignored && cd ignored

/home/rhansen/projects/foo/ignored  <-- I want the Git prompt here
$

In other words:  If I were to use this feature, I'd want to be able to
hide the prompt when I'm in an ignored directory in my dotfiles work
tree, but show the prompt when I'm in an ignored directory in any other
work tree.
