See https://github.com/tc39/proposal-nullish-coalescing/issues/42#issuecomment-513439722.

We could rewrite every a == null as a === null || a === undefined, but that's quite longwinded, and this suffices to call out an edge case that most developers can remain blissfully ignorant of.

The Nullish Coalescing README does not have this problem.
