I'm not sure to understand well the question, then all the code is
accessible here for the windows plugin (this is writen into C/C++ +
win32 api):
The plugin interface with windows explorer:
My C++ class with interface:
Here you have the Qt API:
But I have not GTK API.
With all that's, I thinks you have some example of implementation,
without my english mistake.

That's suppose one overwrite the default? ... not very safe I thinks,
because when it close, if I have well understand, you need re-listen
the dbus deamon.

I thinks it's the more safe, less external to default worker, less
verification, ...
And do like windows, API with return true (have work) or false (have
not work then launch the default dialog).
To this I need somebody write the plugin, because I don't know GTK.

It's why I have provided the windows plugin, it's amazing simple and compact.
Mostly it's just that's:
                return E_INVALIDARG;
                case 0:// copy
                                return E_FAIL;
                case 1:// move
                                return E_FAIL;
                default :
                        return S_OK;
        return S_OK;
