I wish I could get a strong sense of the hype around null safety. Sure, I would like to have the extra expressive option. However, optional has been fine for me. I still barely use it. It has to be at least 3-4 years since I last encountered a null pointer exception in my daily java programming. I feel like there are plenty of other things that pain me on a daily basis that rank far higher on my asks for the language. Collection and stream ergonomics cause constant pain, for example.
