It helps, but ... the library maintainer and the invoker of javac are not the same, so a conscientious (and omniscient and indefatigable) library maintainer will still add @SuppressWarnings to their jdk6+ library the day it is @Deprecated in jdk9. We could add something like @TargetedRelease, which java has historically been reluctant to do. Compare with API conformance macros in C #define _XOPEN_SOURCE 500 placed at the top of every source file.
