The real problem is that there are a lot of clients out there that do not failover to second address in a timely manner. There is NOTHING that says you cannot attempt multiple connections at once or after a short delay. You do NOT have to wait for connect() to fail before attempting a second connection.
Clients that implement Happy Eyeballs (RFC 6555) fast fail between IPv4 and IPv6. There is no reason not to do this whenever you have multiple addresses of the same family rather than when you have a mixture of IPv4 and IPv6 address.
