Fedora + Plank + App launcher

Question

This is how I managed to use 'plank' + an applications launcher in Fedora 20. It workds, but is this 'tip' with 'dbus' appropriate and future proof ?

• Install 'plank' with: sudo yum install plank; (maybe RPM fusion is needed)
• Remove the 'plank' icon with: rm ~/.config/plank/dock1/launchers/plank.dockitem
• Link the launcher with: nano ~/.config/plank/dock1/launchers/show-apps.dockitem

• And add the next text:

  [PlankItemsDockItemPreferences]
  Launcher=file:///usr/share/applications/show-apps.desktop
  

• Create the launcher with: sudo nano /usr/share/applications/show-apps.desktop

• Add the next text:

  [Desktop Entry]
  Version=1.0
  Type=Application
  Name=Show Apps
  Comment=Show applications menu
  Exec=gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell --method org.gnome.Shell.Eval 'Main.overview.toggle();Main.overview.viewSelector._showAppsButton.checked = true;';
  Icon=view-grid-symbolic
  Path=
  Terminal=false
