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 were introduced as syntactic sugar to help us deal with the fact that null exists in the language. In upcoming versions of C# you will be able to opt into nullability. Soon, the default mode of operation in C# will be “things can’t be null”.
Currently developing futuristic smart-device, IoT connected, highway construction site safety system in EU.
Used to work on infrastructure, application architecture and cloud engineering.
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.

The benefit comes when you use Resharper because you can utilize code annotation attributes ([CanBeNull], [NotNull], [ItemCanBeNull], [ItemNotNull])
