Yeah, I think that would work.  Alternatively, we could just be a little better
about parsing path=, so that you can specify arguments and environment varibles
like this

  path=GDK_BACKEND=wayland gnome-terminal --full-screen

similar to what you'd do in a shell.

(hack hack hack)... which I just pushed to master:

    desktop-shell: Break command lines into env vars, executable and arguments

    We now support specifying environment variables and arguments in launchers
    by saying

      path=GDK_BACKEND=wayland gnome-terminal --full-screen

    for example.
