I am going from my memory here...but as I recall, this is how it goes:
The initial kernel boot messages will only show up in one terminal
(whatever one is FIRST in the kernel image loading line)...the other one
"looks" looked up, but once initrd finished its thing, a login prompt

As I recall...only 1 place.
It annoyed me too.

Nope...It does not hang.

Yep...that is not REALLY a problem.
The issue is what happens to the kernel loading messages (at boot time).
If the system is hardwired for ttyS0, and you do not have a serial port,
then you will NEVER see the kernel boot messages.

Now...THAT I disagree with.
It will not crash your system to have the init entry.
The final effect is that IF you happen to have a serial port, then you
can ALWAYS plug in a terminal emulator. All of the enterprise grade
routers and SNMP switches have such serial connectivity. We should have
it as well.
I think that it should be ENABLED by default...and that it should point
to ttyS0. It isn't really a security risk, because you STILL have to
login. As a huge plus, a properly configured external modem would allow
direct asyncronous access to your router, independent of the condition
of the Internet.
My 2 cents worth.
