You are correct that ColdFusion pioneered some modern features, but the author had a specific definition of influence, and states: "Before we start, a quick primer on finding influence. Just knowing that X was the first language with feature Z doesn’t mean that X actually influenced Z.", and then goes on to state that influence only counts if it exists in citations of papers or documentation.
You can absolutely go to town arguing whether or not their definition of influence makes sense, though.
