Thank you Even. You are totally right as always. The reason is the broken
overview.

Denis,
The maximum of nearest downsampling should be <= maximum of full resolution.
Potential explanations:
- your source file has overviews that contain completely different
values than the full resolution image.
- or perhaps your input_raster_to_resize_with_max_val_92.tiff file has a
.aux
$ gdalinfo -stats -json input_raster_to_resize_with_max_val_92.tiff |
jq '.bands[0].metadata[""].STATISTICS_MAXIMUM'
"92"
$ gdal_translate -outsize 1% 1%
input_raster_to_resize_with_max_val_92.tiff output.tif
Input file size is 6845, 10302

Although I'm aware, my personal preference is to avoid that
feature and chain myself to the matrix.org.

But... the cool thing is you don't need to register at matrix.org to be able to
use other matrix servers.
As Sandro says: your osgeo.org-id should also be a valid (osgeo)-matrix id, at
least to communicate with osgeo users, but for what I know also with
matrix.org-user accounts.
And just like d

Dear GDAL Users list members,
We discovered that on Windows and Mac, some versions of GDAL do not properly
decode GRIB2 files if the data is compressed with the JPEG2000 option.
Sample of impacted data:

In fact, it never happens with 3.3.0/3.2.3, ignore it
