Comment (by wenzeslaus):

 Problems reported between Oct 31, 2019 and now:

 * [https://lists.osgeo.org/pipermail/grass-dev/2019-December/093800.html
 ZSTD error]
 * [https://lists.osgeo.org/pipermail/grass-dev/2020-May/094351.html ZSTD
 compression error on Windows]

 Generally speaking, changing the default in minor version became challenge
 for users sharing data (locations, packs) with other users
 ([https://lists.osgeo.org/pipermail/grass-dev/2019-December/093802.html
 ...choice of raster compression method...]) since the requirement was
 version 7.6 compiled //with newly introduced ZSTD//. Expected issues
 between major versions, but not minor ones.

 Even more problems were created by compatibility issues between different
 ZSTD versions.
