Thank you Olivier. It indeed works for osm_cache. My problem is
elsewhere. This is what I get:

$ mapproxy-util export --force --mapproxy-conf=mapproxy.yaml
--source=mnc2010_10cl_cache --grid="srs='EPSG:21781'
bbox=[420000,30000,900000,360000] bbox_srs='EPSG:21781'
res=[250,100,50,20,10,5,2.5,2,1.5,1,0.5,0.25,0.125,0.0625]
origin='nw'" --dest=essai --levels=0 --type=tc

MapBBOXError: not a single tile


If I remove "origin='nw'" from the destination grid specification, I
get no failure.
