add a getEventValue() method to EventContext.cfc as a short cut to

<cfset nameOfCurrentEvent = event.getValue(event.getValue("eventValue")) />

suggested method

<cffunction name="getEventValue" access="public" returnType="any" output="false" hint="I get the current event name">
    <cfreturn variables._state.getValue(variables._state.getValue("eventValue")) />
</cffunction>

The method getInitialEventHandlerName() is (and has been) implemented in the EventContext? for this purpose.
