It looks an awful lot like something that was designed by a sizeable committee made up mostly of academics, most of whom won't have written ten lines of code in as many years. I don't actually know in this case, but I've had to sit and watch standards created in this manner, and Dmitry's description of the RISC-V mess matches their output fairly closely, a chaotic mess that includes every idea everyone on the standards committee has ever had, all made optional so no-one will vote against it when it comes to balloting.
