Never thought of Encyclopedia Britannica for car service information! The danger in running out of gas (which the Encyclopedia apparently lacks) is that if you now deplete the battery under say 20%, you run a risk of battery degradation, similar to what EV owners do when they charge to 100% or discharge under 20%. Affects battery longevity. Not a problem with a single event. What else are you going to do if you run out of fuel? The limp mode is there to help you. If it was a huge problem, the software would brick the car rather than allow it.
Every car on earth can be topped off. How then to prevent damage? A ten cent loop in the vapor recovery system stops any damage. If the emissions systems are damaged, this is a warranty item not borne by the owner, at least in the US. So it is up to the manufacturer to properly design such systems, not on the car owner or gas pump manufacturer to not take advantage of the full tank capacity.
