I disagree that it is ugly: it's a very commonly used shortcut that I
like.  I love it so much that I have the following in my ~/.zshrc:

function - () {
        if test "true" = "$(g rp --is-inside-work-tree 2>/dev/null)"; then
                g co -
                cd - >/dev/null

So, I just

  $ -

to switch back and forth :)
