I tend to suppose this was an intentional change on Graphisoft's part.
The question for me is whether this mode of operation is better/useful for more users than the previous one, or not.
I, for one, found the previous method more useful, was using it quite extensively. At the moment I don't see any obvious situation where that extra polygon would be the result I would need.
I will forward this thread to GS for their consideration.
