It's motivated by liking of reliable systems that keep working when a node fails.

There are a bunch of non-webscale companies that pick mysql over postgresql because they can use either percona xtradb cluster or galera cluster.

Having an open source multi-master solution would mean that postgresql could finally be used over there as well.
