https://stackoverflow.com/questions/31723143/kotlin-uses-runtime-assertions-for-null-checking-performance-overhead is this is still possible?

Have a look at Christophe Beyls's article about it. (middle section is about null safety) https://medium.com/@BladeCoder/exploring-kotlins-hidden-costs-part-2-324a4a50b70
