Drops the bounded multi-backend scheduler split from the feature list: upstream 992cb50 (ggml-org#28387) deleted the input-count check outright, so split boundaries can no longer drift with the growing inputs_capacity and the local change has nothing left to do. Records that upstream independently built and then reverted routed-MoE MMQ tile sizing (ggml-org#24546, reverted by ggml-org#28551). The revert was about where the logic lives, not whether it works -- the objection was that it changed kernel configurations instead of deciding on the host -- and that PR excluded gfx1151 outright, so its own gfx1151 operator measurements remain the best evidence for the idea here.
