The code output shouldn’t become incorrect because of this, so there is no “failure”. A future version of Julia could make the flag emit an error, and by then that wouldn’t have much of an impact on users. The performance may change, which can be true from version-to-version anyway.
Caching of native code is a huge improvement! Good job to the Julia team for getting it done.
Maybe it’s better to emit an error instead? You know, don’t make things fail silently.
