Not exactly a strong argument if you need like 5 qualifications to demonstrate the issue. If the right node fails, if it happens right as you walk up, if it's raining, if your porch is uncovered, if your door doesn't have an immediate fallback... I'm sure someone will be affected because of the law of large numbers, but it seems like an unlikely scenario to base a purchasing decision on.

A light switch not working for 30 seconds, or a door not opening for 30 seconds, even if only sporadically, is a significant loss of life quality, no qualifiers needed.
