As with some peculiar memory subsystems, botched device interfaces, or 80 core processors, I'd say that perhaps the architectural features are there to meet the needs of hardware designers and are not actually designed to run the programs people are actually writing. Perhaps someone told them the software people wanted some of this stuff, but I've got my doubts!
