Then work through the implications of what you observe.Go test your IPv4 code against a half broken multi-homed server. There is no difference.
Which is why the common and successful strategy in engineering a reliable IPv4 system is to use a single IP address for each service and let BGP handle multihoming. Using a single IP address is no longer possible for dual-stacked hosts, so your dual stacked client code has to handle it instead.
With dual stack [...] no more ignoring the issue.
