This is true. This is also rare in modern code, and impossible with standard library. Other libraries too are expected to adhere to nullability, which is a default whenever you create a new project, and many use the same WarningsAsErrors: nullable option on top of Nullable: enable set everywhere. At the end of the day, scenarios like a library spawning a Goroutine which tries to dereference a null where it doesn't expect and experiencing an unhandled panic, crashing the application, are practically impossible in .NET. It is not necessarily watertight, especially around JSON serialization, but it certainly evokes a "can't believe you guys still struggle with nulls/nils" kind of reaction.
