So, while not all simulations you do require timing, there are simulation needs throughout the design process that does need them. When you only do functional simulations, timing is rarely important and the gained simulation speed is the benefit. Like all good tools, wise usage and timing of use is the key. You want as many cool tools in the toolbox, but you also want to know when to apply which tool.
