At present, I don't think I do.  It allowed a useful space optimization for my 
read cap index files, but for other reasons I've done away with that.

However, I wouldn't be surprised if someone else finds a need for it, and I 
disagree that it's a particularly dangerous feature.  There are a LOT of 
things that someone writing a client can do to screw themselves, this is just 
another of them.

For now, though, I don't think there's a need for it.
