Hi Daniel,
This was discussed a few months ago in this thread:
https://groups.google.com/forum/#!topic/pgxn-users/vrD9GAczW9Q
In other words, it's not stuck but kinda abandoned / in maintenance only
mode, and will probably disappear entirely in the near future.
There was a brief discussion about how to address some of the issues
described in that thread, but nothing really changed.
regards
Tomas
