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.
I would suspect that zsh has more "posixly correct" mode, with which
it _can_ run POSIX shell scripts, and I would imagine that this
"$status is an alias $?" business is disabled in that mode?
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.
