Spintendo, you can still do this if you use utorrent. It's in the 'peers' tab down at the bottom. Granted, you have to actually connect to the torrent to see the details, but it's not as if you have to keep downloading it if you don't like the stats — just stop the torrent and/or delete it.
Actually, this will not give you the complete list unfortunately. Using the "Peers" tab will only provide you with a list of the peers for which you are presently connected. Depending on the torrent, it may not always be possible to connect to all of the peers in the swarm for a number of possible reasons. Again as I said, although it is gone for now, this does not necessarily mean that it will be forever that way. I cannot say for sure as there is no set plan, however it is something that can be discussed among the staff as a possibility to implement in a slightly different manner.
