Yes, that should be correct, it is true for llvmpipe as well. llvmpipe references clip_halfz directly because it also infers from it it's really d3d10 hence infers from that depth clamp is always enabled, it also needs this for deriving said depth clamp min/max. This is quite a fishy area though there (the depth clamp differences between GL and D3D10 are weird and not properly expressed really in gallium). But I guess those differences would be more related to the broken / misspecified NV_depth_range extension... So, looks good to me.
