Disabling IPv6 probably isn't an acceptable workaround anyway. What happens if both an IPv4 and IPv6 IP address is listed? Postfix may still use other network interfaces not listed (IP addresses).
Changing the parameter name wouldn't be a bad idea either seeing parameter values are actually IP addresses and not interface names, as the parameter name suggests.
