The goal is to reduce the confusion between the high level navigation manager/listener which provide events about the navigation to WebDriver BiDi with some logic specific to BiDi and the underlying listeners directly monitoring the platform notifications. In the next patch in the stack we need to introduce an alternate way to listen to those platform notifications so having more distinct names could be useful.
