IMO, there's no need for single-action capability on a defensive revolver. OTOH, there is a use for the hammer spur on a defensive revolver, even one that's been rendered DAO. It permits the shooter, during an administrative load/reload, to pull the hammer back far enough to free the cylinder to rotate and verify that the rounds are seated and that there are no high primers. There isn't universal agreement on the usefulness of this, but I find it useful.
