We currently do not build mathplotlib with any backend. This can be very confusing for users. They will try to use matplotlib and it will simply display nothing (see #51337). We should ship at least one backend. `tk` was chosen somewhat arbitrarily. The gtk backend is problematic (see https://github.com/NixOS/nixpkgs/issues/50959#issuecomment-441327767) so tkinter seems like a good choice. There is already a backend provided on darwin so there is no reason to include tk there.
