In practice it doesn't, hence the PR.  The API currently provides no suitable method for preventing the egg plop sound, retrieving the chicken laying the egg, or altering the delay between egg drops.  As I've mentioned, existing workarounds are horribly inefficient and - in some places - insufficient.  There are numerous use-cases (which I'd be happy to discuss in depth), a number of which have been detailed several times over in FBO posts.
