would it not be a good idea to NOT disclosure service versions?

you will more and more have the "problem" of 3rd party
security scans to your servers and currently in the case
of openssh the only solution is to tkae the F16-src-rpm
and rebuild it for your F15 machines

however - why do we spit the current running versions to everyone?

Spitting out versions makes your OWN network monitor easier, as you
can depend on version strings, instead of brute forcing unversioned
services to do a security scan/audit.

With or without versions, attackers will always brute force anyway.

Hiding therefor services no purpose other then make your own process of
inventory harder.
