The direct answer is because zsh didn't even begin to claim any level
of POSIX compliance until those constraints began to be added to the
"sh" emulation mode, more than 10 years after the shell was written.
The indirect answer is because this is a pretty dark corner case, and
there is no organized effort to examine the entire POSIX spec for
items that haven't yet been included. What effort there has been has
been focused on shell scripting more than interactive use.
