failover from IP to IP is a good thing, agree with you. But if we could
use steward as a mediator and an arbitrator for cluster service groups it
might give you
more possibilities for auto failover in CONNECTED mode

Having taught Global Clustering and its predecessor, I would prefer
to see WAC have the ability to failover from one IP to another or
make multiple connections over 2 or 3 IPs for higher redundancy.
Keep in mind that DR is not HA If the WAC loses the connection, you
would get notification and can fix the problem or online SGs at the
remote site as appropriate.

Hello all!
Only WAC now ensures communication between clusters. But it is not
always good. If WAC is broken it is still possible to use
heartbeats (through SRDF ping or steward) but there is no other ways
of starting service groups on remote cluster. I don't mean Auto
failover option between clusters which is not recommended by Symantec,
If steward could handle service group information between clusters
. It could be really a useful thing!
Kind regards, Pavel Tsvetkov
