re: Dealing with Nothing in C# - The Null Object Pattern VIEW POST

re: Nullable value types introduced the concept of null where previously a value couldn’t be null. (It’s essentially an option type.) The rest of these...

So that’s exactly what I think you’re missing here. In upcoming versions, you won’t need those annotations. Take some time to look into Nullable reference types.

I think it's far from being ready. Especailly if it introduces breaking changes. Switching midsets is difficult and if you hide a feature behind a compiler switch it's not going to work.

By the way John Skeet found 2 bugs straight away...
