The Mesa Gallium drivers just care about the STATIC/DYNAMIC/DRAW part
of the usage hint, and not so much about READ/DRAW/COPY. I can't say
if that will necessarily always stay that way though. I know the
proprietary NVIDIA driver does at least complain through
ARB_debug_output if the detected usage doesn't match the usage hint.
