Go have your talk [1]. But that's a pretty weak argument anyway given that: 1. Other languages also do not have this distinction (Python for example AFAIK), 2. It's relatively useless. I get the value of it in JavaScript which has a lot of asynchronous code and frontend where the behavior may indeed be very different between null and undefined, but in a server-side application I don't think the nuance is necessary at runtime, and potential programming mistakes involving that can be caught by a linter.
