A couple of months ago we made the decision to stop using mysql-mmm on one of our client sites. We had been burned by a couple of incidents where automatic failover had caused more problems than we had imagined it would solve. Data ended up being written to the wrong server a few times, causing a bit of a nightmare to merge the forked database after the fact. Although we had other concerns about mysql-mmm, a major factor in our decision was our assessment that in our specific case of assigning MySQL master-slave IP addresses, human-triggered manual failover was essentially as good as automatic failover, and carried much less unexpected risks.
