Probably the person with the emergency needing immediate
assistance has a different opinion.  Operators that don't want
to be bothered by other people's emergencies probably would see
it as a nuisance.

So they will only turn on the emergency alert function when they
think someone they care about is about to have an emergency?

Yep, Everyone in the net may have information that others do not
have.  In an emergency presented to the APRS local network,
everyone involved needs to take that ssecond or so to determine
if they are in the position to offer assistance.

I have only seen it happen ONCE in 15 years.  And it was an
overturned vehicled down in a valley in Pennsylvania needing
immediate assistance.  In 15 years, not that big of a deal
(until you need it).  It's not a proposal.  That is the way most
APRS clients have reacted to the emergency signal.
