Right, and I suspect that it's very rare for zsh to be used as /bin/sh. I've heard of people doing it just to see what would fail, but not of anybody doing that for regular use.

Yes, if zsh is invoked as either "sh" or "ksh" it attempts to emulate the usual semantics of the named shell. One of the differences is that $status isn't special in the emulation modes.
