AxisMenu in backend_tkagg

Hello

I am preparing the Tkinter implementation of my MultiFigureManager

In backend_tkagg there is AxisMenu
Looking throught all the matplotlib code I do not see any place where
this is used, not even an example
Is this something that we want to keep around? does somebody use it?

Just as a reminder to get feedback on the multifigure-manager
Compare: https://github.com/fariza/matplotlib/compare/tabbed-gtk3-figuremanager
PR: https://github.com/matplotlib/matplotlib/pull/2465

Thanks
Federico

Using git blame, I can see that the AxisMenu class was last touched by John Hunter back in 2004, during a massive restructuring of the code-base. It looks like at that time, there were only 3 interactive backends: Gtk, Wx and TkAgg. Maybe someone with a much longer history than I could chime in on the purpose of this class.
