You answer your own question.  Something as simple as changing banners can
stop some automated scripts and keep out some wannabe script-kiddies.  You
are right that it doesn't provide any *real* security, but it does help to
stop some scripts and slow down some attackers.  And although it might be a
small step, the more steps can add to slow down an attacker, the better
chance I have of keeping them out.  Maybe they'll get tired of peeling
through the layers.  Maybe it thwarts a dumb script.  I run my webserver on
a different port than 80.  It may not add any "security", but it keeps Code
Red and Nimda from clogging my logs all day.

Let's face it, most attacks come from script-kiddies looking for the weakest
host, not real crackers targeting your domain.  And if modifying a banner or
changing a port number keeps out one or the other, than it is worth it.
I'll still use other means to beef up my *real* security, but every little
bit helps.

        If they're harmless, they are no threat.  If there is no threat
from the beginning, then please explain the security benefit.

        Besides, what good is it if a banner alteration turns away Joe or
Jane Scriptkiddy if the next visitor is Nimda on rollerskates?

        My assessment stands: security through obscurity ain't.
