Comment(by robe):

 pramsey has commented on this on github:

 repeated here for completeness: https://github.com/postgis/postgis/pull/27

 "OK, so I haven't actually run this, but reading it, it seems to take over
 all geodesic calculations, the area calculation explicitly and the
 length/distance/projection ones by taking over the core edge routines for
 geodetic calculations. I thought some performance work showed that there
 was a speed penalty for this approach and we were looking at just
 replacing area."
