I'm assuming that all the libraryLoader's deferred actions fall into a similar
TODO? maybe mark registerDeferredAction with the TODO or even add a @deprecated
to it?

Add a TODO to [registerDeferredAction].

-        compiler.enqueuer.resolution.addDeferredAction(element, () {
+        compiler.libraryLoader
+            .registerDeferredAction(new DeferredAction(element, () {
           annotation.ensureResolved(compiler.resolution);
           handler.validate(compiler, element, annotation,
               compiler.constants.getConstantValue(annotation.constant));
-        });
+        }));
         return result;
