Xrender is hardware-accelerated on an increasingly small number of devices, and even SNA, the flagship hardware-accelerated implementation in the Intel driver fell back to software rasterization extremely frequently [0]. In practice it wasn't worth it, and it was extremely buggy, hence why it fell into disrepair. The semantics of Xrender simply don't match with what modern GPUs give you, even ones with 2D pipelines.
