Nullable is just a different loadout state in Railway Orientated Programming. So, no reason to put different flavours of state into the language directly, when its a solved thing since (checks slides) 2012. There is just rails - going to A or going to B, depending on the trains loadout.

If you have language-wars about a concept going in and out of existence, that is a hint that there is demand and the language does not properly handle the demand or when it handles it, it creates mental overload.
