To be clear (to other readers, if not you), the optionality of "in word ..." isn't a zsh extension. It's well established and quite portable [*]. The issue is that zsh's "for" command accepts multiple variables, which means that omitting the "in" keyword in zsh produces a differently valid "for" command, while in other shells it produces an invalid one. (I'm not aware of any options or tricks to accomplish either of the behaviors you asked for, but I'll let someone else provide a more definitive answer.)
