-   * TODO(cpovirk): Consider @DoNotCall -- or probably some other static analysis, given the problem
-   * discussed in the rest of this comment.
-   *
-   * The problem: isEqualTo(null) resolves to this overload (since this overload is more specific
-   * than isEqualTo(Object)), so @DoNotCall would break all assertions of that form.
+   * NOTE: we don't actually mark this as deprecated (or @DoNotCall) because isEqualTo(null)
+   * resolves to this overload (since this overload is more specific than isEqualTo(Object)).
    *
    * To address that, we could try also adding something like `<NullT extends Impossible &
    * MessageLite.Builder> void isEqualTo(NullT)` and hoping that isEqualTo(null) would resolve to
    * that instead. That would also have the benefit of making isEqualTo(null) not produce a
    * deprecation warning (though of course people "should" use isNull(): b/17294077). But yuck.
    *
-   * Given the null issue, maybe we should never have added this overload in the first place,
-   * instead adding static analysis specific to MessageLite-MessageLite.Builder comparisons. (Sadly,
-   * we can't remove it now without breaking binary compatibility.)
-   *
-   * Still, we could add static analysis to produce a compile error for isEqualTo(Builder) this even
-   * today, even without using @DoNotCall. And then we could consider removing @Deprecated to stop
-   * spamming the people who call isEqualTo(null).
+   * Given the null issue, maybe we should never have added this overload in the first place!
+   * In cl/839267698, we added static analysis to MessageLite-MessageLite.Builder comparisons.
+   * However, we cannot remove this method without breaking binary compatibility.
