Well, my view is that if somebody wants an alternative behavior
besides dropping the connection, they can write a patch to provide
that as an additional option. That, too, has been discussed before.
But the fact that somebody might want that doesn't make this a bad or
useless behavior. Indeed, I'd venture that more people would want
this than would want that.
