Our codebase uses `null` extensively to represent an absence of value or optionality of the argument.
We utilize nullness annotations in Java code and somewhat rely on IDE warnings to guide us.
However, the Java code we have is not fully annotated, which causes several consequences:
* IDE warnings can be misleading
* Redundant null checks may increase binary size, hurt performance, and increase cognitive load for readers

                    errors.add(req.getMessage());

                break;
            case WARNING:
                if (!warnings.contains(req.getMessage())) {
                    warnings.add(req.getMessage());
                }
                break;
            default:
                throw new IllegalArgumentException("Unknown severity: " + req.getSeverity());

                warnings << "Return nullability changed from nullable to null-unmarked"
            }
        }
