[gdal-dev] Call for 4.0 ideas

[Even Rouault]

| But I have more troubles to understand why breaking code that use 
spatial_ref for decades without any real need

Have you ever looked at the mess in the netcdf driver? Aligning with 
recommendations from standards, especially on the write side, and 
helping to reduce a bit code bloat (although mostly symbolic here) is 
helpful.

Another thing is that as currently we write both crs_wkt and 
spatial_ref, this can puzzle human or software readers, and that could 
result in inconsistencies if a writer would update one of the attribute 
without the other one.

I'd suggest people with interest in a particular driver do their own 
pass and add their suggestions to the meta-ticket (there have already 
been suggestions to change GTiff defaults to use LZW and tiling).

| And do another deprecation/cull through unused drivers?

maybe, but do we have data points to assess what can be deprecated? 
(other than me blowing off out of frustration occasionally and randomly 
picking candidates :-) :-))
