Ah, that would include me :) If the stonith device fails to fence the failing node then there is no failover and you get zero availability. The probability that that happens is much higher when using a device such as external/ssh since it depends on both the network availability and the OS health. I'll leave it to you to figure out in how many ways these two dependencies can hinder a fencing operation.
