The case of GeoServer is also strange

sample - the response is huge (the whole geotiff?).

An open Geoserver with a DEM of Finland is available for testing at
http://avoindata.maanmittauslaitos.fi/geoserver/wcs?service=WCS&version=2.0.1&request=GetCapabilities
Same thing with this server (I'm still testing with version 1.1), except
that it is nice enough to let me know that
ERROR 1: This request is trying to generate too much data, the limit is
488.28MB but the actual amount of bytes to be written in the output is
18479MB
With the help of GeoServer demo tool in its admin panel, it seems
necessary to add GridCRS to the request
http://avoindata.maanmittauslaitos.fi/geoserver/wcs?SERVICE=WCS&VERSION=1.1.0&REQUEST=GetCoverage&IDENTIFIER=korkeusmalli_10m%3Akorkeusmalli_10m&FORMAT=image%2Ftiff&BOUNDINGBOX=44005,7781985,44015,7781995,urn:ogc:def:crs:EPSG::3067&RangeSubset=contents&GridBaseCRS=urn:ogc:def:crs:EPSG::3067&GridType=urn:ogc:def:method:WCS:1.1:2dSimpleGrid&GridOffsets=20.0,-20.0&GridCS=urn:ogc:def:cs:OGC:0.0:Grid2dSquareCS
GridCRS should be optional but in practise GeoServer seems to require it.
