It doesn't look like this will ever be replaced, and there seems some
chance that GNOME applications will just stop having recent files menu
items:

I've chosen to just do this in code, in the examples. However, we need
to use the C API to set the GAction's name on the toolbar button:
https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/menus/main_menu/examplewindow.cc
because we cannot yet break the ABI to add Gtk::Actionable as a base
class for several classes:
https://git.gnome.org/browse/gtkmm/commit/?id=3381c0aea10891a2dccc49b5e450fd497a3cb807

So, I think we can leave these classes deprecated after all. I'll post
separately about the new API.
