Also not trying to be argumentative, because you are right, there is no guarantee that a second strike will fire the round. However there are other reasons for FTF other than a "dead" primer - the most common of the ammo-related reasons being a primer not fully seated. The vast majority of the time the first strike will fully seat it and a second strike will fire it.
There can also be mechanical issues with the gun that cause light strikes. In my experience, if a light first strike has already dimpled the primer cup, a second strike will make it fire off the majority of the time.
Presumably a lot of guns aren't second strike capable simply because making them so is a little more complicated - making the trigger capable of fully cocking and releasing the striker/hammer is a little more involved than making the action of racking the slide the mechanism that pre-loads the striker and sets the sear makes for a simpler mechanism.
Just curious, but what do you see as being such a negative about second strike? If you can train to instantly 'tap-rack-bang" for a malfunction, then surely you can train to try a second trigger pull and THEN default to "tap-rack-bang". Seems like adding that one additional trigger pull to the training shouldn't be a big issue.
