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.
