And this statement is exactly why I believe you are wrong.

Because *I* think messages to the console is more important than messages
to the logs. Several of my servers are only monitored by the console. I
seldom look at the logs on those machines.

This is a policy decision, and must be made by user space. Your use case is
not applicable to everyone else's use case. And should not be set in stone
by the kernel.
