Make some way to generate tiles beyond native zoom limit.
For years we could make tiles from zoom 2 all the way to zoom level 10.
Now even at the latest version there I find no way to generate tiles beyond native zoom limit level.
Steps to reproduce the problem.
Image used is over whole of Slovenia (extent: [370000.0, 20000.0, 630000.0, 200000.0]) in EPSG:3912 geo-system. Sorry for long not so important print of gdalinfo. I tried to submit original tif file itself, but it is too big:

Such file is then used in gdal2tiles (within OSGeo4W Shell):
E:\water-images>gdal2tiles --profile raster --s_srs "EPSG:3912" --zoom 2-10 --no-kml --webviewer openlayers --processes=8 "2021\2021-colors.tif" "2021\tiles" --exclude
Clamping max zoom level to 8
Generating Base Tiles:
I expected some way or argument to be able to generate zoom levels 9 and 10 like for years before. But now we do have native zoom limit and are unable to do so.

This GDAL/OGR is installed from download QGIS site for Windows 10. I used OSGeo4W Network Installer.
