Re: C# and especially F#, unfortunately the runtime they run on supports nullable references front-and-center, so even if your code doesn't use nullable references, the standard library and your dependencies will. Of course you can write translation code at the boundaries between your code and the other code to convert `OtherCode.MightBeNullType` to `OtherCode.MightBeNullType option`, but that still doesn't help for `OtherCode.MightBeNullType`'s fields unless you redefine all the types and write conversion functions for all of them.
