[gdal-dev] Enabling default compression for COG ?

should we enable a default compression scheme for the COG driver ? I've 
heard people "complaining" about that, or people just not realizing that 
specifying a compression method was something reasonable to do. Likely a 
lossless one to be conservative. ZSTD is probably not reasonable as it's 
too non-standard outside of the GDAL/libtiff world. So the choice would 
go basically between LZW or DEFLATE. LZW has probably the best 
compatibility profile (but the less efficient). I guess that most 
browser based solutions would handle it ? Thoughts ?
