The reason why it wasn't implemented for -done and -forwarded is because the psuedoheader parsing for -done is pretty different, and we aren't doing any parsing for -forwarded. There's no technical reason why it couldn't be done for both, but at the time I implemented it, I didn't fully understand how much utility people would find from it.
