Sure. If you work on this extension after CF3, and it reveals that the
custom scan stuff needs some adjustments, there would be time to do that
in CF4. The policy about what can be submitted in CF4 is that we don't
want new major features that no one has seen before, not that you can't
make fixes to previously submitted stuff. Something like a new hook
in vacuum wouldn't be a "major feature", anyway.
