What's confusing about that? It's null, just two different kinds with slightly different meanings. Is having two boolean values also confusing?! Should we simplify it?

I mean I can get behind trying to remove null entirely and replacing it with better concepts, but I cannot understand why having one more null value suddenly makes it confusing. You don't even have to care in 95% of the cases, and it can be useful in the other 5%.

Honestly, it looks more like some kind of misguided purism to me.
