Yup, unfortunately for us there is a lot of C# code written without NRT. If all of your code utilizes NRT and you respect the warnings, you can nearly eliminate issues related to null. There are some paper cuts around generics, but generally it has been working quite well for me. Our entire code base has NRT enabled and the only place where null sneaks in is with EF Core missing includes. This is actually kinda nice because if you get a null-whatever exception, 99% of the time it's a missing include.
