Can't you just choose not to wrap that vfunc in your C# binding?

I think this is similar to a problem we have in gtkmm. When a GTK+
widget implements an extra GInterface, we can't just add a base class to
our existing C++ class, because that would break ABI in C++. So we just
don't wrap it, and tell people to use the C API when they need to use
that part of the API. It doesn't happen much, luckily.
