SplDoublyLinkedList missing insertBefore/After

I have just noticed that the current SPL inplementation of a DoublyLinkedList does not include methods to insert nodes into the middle of the list (insertBefore, insertAfter). After mentioning it I ran into a few people and other outbursts on the internet of more people who saw this and complained about it. I found a bug from 2009 (https://bugs.php.net/bug.php?id=48358) which mentions the case and has no Core response at all. I ask two questions: 1) Why was this bug never replied to, is there some reason these methods should not be implemented? 2) Is anyone willing to put up a patch for this? I imagine that if you are familiar with C and PHP source this is a quick implementation as its standard logic documented everywhere. I'm not familiar enough with the PHP source to do this myself, hence I'm asking for anyone willing to "champion" the patch.
