This is the issue I raised with #3815. I don't think it is a good idea 
to use something as default if it is not a required dependency. As I 
described this can lead to the issue that without the user knowing it 
(e.g. using GRASS GIS that was compiled by someone (package manager, 
etc) with --with-zstd=yes) she creates raster maps that are compressed 
with zstd. If these maps are then moved to a machine that doesn't have 
zstd, the data is unusable.

That is why I proposed to make it a requirement. The other alternative, 
IMHO, would be to make ZLIB the default compression again and leave the 
use of ZSTD to power users.
