The first two steps (with shuf instead of shuff)  only work if
array elements don't contain backslashes nor newline and are not
empty and the first one doesn't start with "-".

Yes, that's not what read -A does.

You could do things like:

array=("${(0@)$(printf '%s\0' "$array[@]" | shuf -z)[1,-2]}")

But that would still not work for array elements containing
NULs.
