Use `Objects.requireNonNull` statement or `Preconditions` rather than `assert` or `@SuppressWarning` annotation to suppress if possible.

For gradual adoption, enable checks project-by-project.
Do not rely on `@NullMarked` annotations.
Only enable checks for a project if all its dependencies have checks enabled, in order to avoid back-and-forth when refining the annotations.
