[gdal-dev] follow warp with translate still?

[Even Rouault]

Matt,

There has been an enhancement in gdalwarp to support writing directly to 
drivers, like COG, that supports only the CreateCopy mode. So you don't 
need the 2 step process and can directly gdalwarp -of COG (it will more 
or less do the 2 steps internally)

If you output to regular GTiff, the 2 step process might be needed to 
get the best compression
