 * A [ConeDiagnostic] that is never reported.
 * It is used when multiple FIR nodes, like a type ref and a reference, would otherwise contain the same diagnostic,
 * which would lead to duplicate diagnostics being reported.
 *
 * Call sites should document which FIR element's diagnostic this is duplicating and why the usage won't lead to missed diagnostics.
