IMO there really needs to be a way to mark all variables non-null by default at package or at least a file level. Otherwise there will be a strong safety argument for always using T! syntax on almost every variable and this will just be a lot of noise.

i don’t think it will be that bad. we have a standard in our projects today that all java variables in code we own are not null. if you would like to have a nullable variable, you must annotate it with @Null

this is only an issue at the boundaries of our code where we interact with libraries. i imagine that will be the case with this new syntax as well

If I understand you, then you're not getting any compiler check support for misuses, correct?

I suppose an aggressive linter could assume unmarked should be treated as non-null and at least demand nullability markup where needed.
