That's just an habit for people who have been forced to deal with BE
CPUs.

The sad thing is that BE CPUs have been designed by folks who blindly
expanded BCD computing without understanding the hardware
implications.

Unfortunately they managed to inflict BE to the network protocols
which in turn manifested the only excuse of keeping the BE nonsense
alive.

Thanks,
