On the topic of network messages that SFOS doesn't implement: the other day I was reading about the missile that overflew Japan, and citizens living in the area received an alert on their phones. This reminded me that I've seen those alerts before, on Android phones, for flood warnings or Amber alerts. This seems like something SFOS should implement as well; it would not be good to be less safe in the event of a disaster because our OS did not display the warning.
