Showing the coin at the top has not been removed. If CGWatcher is able to determine the coin being mined, it will display it. If you're referring to multi-coin pools, if the pool is not currently providing the information then CGWatcher can't display it. For example, the data hashco.ws provided me is down at the moment, so it cannot display the current hashco.ws coin. I've emailed them and hopefully it is something they can fix quickly.
