+   * or extract a variable, and put the suppression on that. However, a local variable typically
+   * doesn't work: Because nullness analyses typically infer the nullness of local variables,
+   * there's no way to assign a {@code @Nullable T} to a field {@code T foo;} and instruct the
+   * analysis that that means "plain {@code T}" rather than the inferred type {@code @Nullable T}.
+   * (Even if supported added {@code @NonNull}, that would not help, since the problem case
