How?
Because when charging the voltage goes above 7.4 volts.
I agree on most points, but are there still chargers around that are not immune to reverse polarity and shorting?
That is true, however there's still that risk of shorting out producing a significant spark and an electric shock, it's not a pleasant experience being zapped by a charger, sure it may not harm you but still a hazard. I know it shouldn't happen but for some reason I received a zap from it, I no longer have that charger btw.
Also, what if you drop one of your tools and it shorts the terminal of the battery while it's charging in the car, that could also lead to the battery shorting out, which again could have dire consequences.

Likewise, makes sense to minimise the risk of damaging your equipment rather than gaining a few moments of time.
