DRI2 does buffer allocation in the X server. This ensures that that multiple (presumably cooperating) applications drawing to the same window will see the same buffers, as is required by the GLX extension. We suspected that this wasn’t all that necessary, and it turns out to have been broken several years ago. This is the traditional way in X to phase out undesirable code, and provides an excellent opportunity to revisit the original design.
