This is unlikely to be implemented in the way you describe.
I can't simulate it using the 'Cut Paths operation either!
(Cut paths seems to lop off rather than divide, this is
arguably surprising behaviour and therefore a bug).
If you really need this in Inkscape, I suggest that you:
1) Organise the requests so that there is one per entry in
the tracker.
2) Devise a UI for your 'Carving Knife' or 'Chain Saw' tool:
Possibly harder than you might think ...
I can't see this being made a priority item, but you never know.
In the mean time, you might find that in degenerate cases
such as a vertical or horizontal line, you might be able to
run a perl script on the XML.
