Kind of. It's actually multiple tools in one. One to broadcast your pricefeed (the price of HIVE on Hive - the blockchain - is determined that way), one to watch your witness servers in case they're misbehaving and another one to manage your witness (i.e. in case the previous is the case). So partly to make it easier and partly required. I'm not the only who builds these tools, but I think mine are a good choice.
