Bit like arguing that another keyboard layout would be better and it would if your starting from scratch, but people tend to go with what they know and that propergates as accepted and good enough, a standard. Hence, whilst there are better layouts for keyboard, we still have QWERTY. Much the same with argument here, sure GA would be better, and maybe that may well come about, but alas quaternions are somewhat known by the many over the few and a bit of a QWERTY situation plays out.
