Good find, but...

- it is marked as undocumented. Means, it can return pretty much anything, including nothing. 
- it is marked as deprecated. 

Whether this is sufficient or not, well, Docs team can decide on adding a note.I would say its OK as it is. Thus, setting to "not a bug".

So, there is no plan to implement this function at all ?

On 5.6.12, this when calling the function, it returns an error instead of an empty array. Documentation should be updated opened a doc bug here https://bugs.php.net/bug.php?id=70352
