Yup, it's definitely taken a lot longer to get to this than I thought.
It is, however, still in the queue.

If you're curious about my thought process on this, it's pretty simple:
1) These codecs - while cool and useful - are not nearly as widely
used as say, codec_g729.
2) They require an upgrade to the new media improvements that were
made in 13, plus testing, etc. - which isn't hard but does take time.
3) And frankly, I'm putting Digium developer's time on improving open
source Asterisk, which means fixing more critical bugs. When there
aren't as many critical bugs, we can allocate someone's time to doing
the upgrade on those codecs.

If you'd like to make that picture change faster, you can always pitch
in on the issue tracker.
