...this for sure is a point one could discuss in various directions.  
the decision for this naming scheme has been made to define a unique 
extension for native saga file formats, that immediately and 
transparently says what file type it represents. the first two letters 
'sg' tell that it's a saga format after the '-' a three letter 
combination follows that specifies the data type. and if it is a 
compressed file '-z' is added. this is currently implemented for
  sg-grd-z = compressed grid
  sg-gds = grid collection
  sg-gds-z = compressed grid collection
  sg-pts = point cloud
  sg-pts-z = compressed point cloud

it might be followed in future by file formats for tin ('sg-tin') and 
vector data ('sg-shp').

> Is anyone planning to add support for this to gdal?
the compressed versions are simply the uncompressed files zipped into 
one file. therefore it should not be too complicated to add gdal support 
for compressed saga grids.
