Apparently its not needed for reading data:
"As part of the netcdf-c library, the quantize algorithms are available for
netCDF/HDF5 files, and the new ncZarr format, and produce data files that
are fully backward compatible for all versions of netcdf-c since 4.0, and
also fully compatible with netcdf-Java."
