Some of that has to be engineers taking the piss. We are all the same kind of geek-ass bastard, and we love this kind of stupid thing.
IIRC, IBM’s PowerPC chips had some of their instructions renamed in 1994. There were some very plausible motives given for changing how mnemonics worked. Mentioning flag names was boilerplate, abbreviating “ex-” words as X was too American, that sort of thing. So officially, there’s no particular reason the Enforce In-order Execution of Input / Output command is EIEIO.
