[postgis-devel] <-> operator for geography

I have a index on a geography column and I would like to use it to pull 
out nearest neighbors from a given point.  With a geometry column this can 
be done by ORDER BY location <-> 'point', but there is not an equivalent 
operator for geography.  Is there a technical reason for this or is this 
just because geography is a newer type and doesn't have full support yet.
