There is no such function at the moment. I'm not really sure how it
would work either. Its normally the case that nautilus calls into the
module when it needs some information, but what you propose is the
opposite. But this means the extension must be running already so that
it can call nautilus, and that is not typically the case.

How would you detect that the menus need refreshing? I guess it might be
possible to register a source in the mainloop for this.

Anyway, i'm not conceptually against having this, even if i'm not
immediately sure how it would be implemented. I'll gladly take patches
for it.
