Michel Fortin implemented it and created a pull request for it a number of 
months ago, but it has yet to go anywhere. I don't know if Walter has even 
looked at it yet. But it's a big enough change that he's probably going to 
want to study it in detail, so my guess is that he's been putting it off.
